What is the angle of 1
Answer:
100°
Step-by-step explanation:
m L 1 = (180-100) + 20 = 80+20 = 100°
Find m∠1 and m∠2. Tell which theorem can be used.
Answer:
1 = 117 ( vertically opposite angles are equal )
2 = 117 ( corresponding angles are always equal )
Step-by-step explanation:
Answer:
angle one=122 because it is using the alternate interior angle theorem
angle 2=58 because it is using the consecutive interior angle theorem
hope this helps
have a good day :)
Step-by-step explanation:
remember consecutive=same sine 122 is on the same side of angle 2 just substract 180-122=58
since 122 is on the opposite side of angle 1 it's going to be alternate something so since it's on the inside its going to be alternate interior angle
-4.3 + x equals 0 selected place on the number line to positive value of x
Answer:
x is equal to 4.3
Step-by-step explanation:
since it's -4.3 + x is equal to 0
you take -4.3 to the other side of the equal sign which makes it positive and x is equal to 4.3
Kendra spent ⅓ of her allowance on a book and ⅖ on a snack. If she had four dollars remaining after purchasing a book and snack, what was the total amount of her allowance?
Answer: 15$
Step-by-step explanation:
Given
Kendra spent one-third of allowance on a book and two-fifth on snack.
If she had four dollar remaining after purchase
Suppose x is the original amount
[tex]\therefore x-\dfrac{x}{3}-\dfrac{2x}{5}=4\\\\\Rightarrow \dfrac{15x-5x-6x}{15}=4\\\\\Rightarrow 4x=60\\\Rightarrow x=15[/tex]
Thus, 15$ was her total allowance.

Answer: 5 has a value of 50 000 2.
Can someone help me with this, pleasee.
Answer:
120°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for third angle
third angle = 180° - (20 + 40)° = 180° - 60° = 120°

A ladder that is 14 feet long is placed against a building. The bottom of the ladder is 6 feet from the base of the building.
In feet, how high up the side of the building is the top of the ladder? Round to the nearest tenth of a foot.
Answer:
12.7ft
Step-by-step explanation:
this involves the Pythagoras theorem: base² x height² = hypotenuse²
b² x h² = hyp²
6² x h² = 14²
36 x h² = 196
h² = 196 - 36
h² = 160
h = square root of 160
h = 12.65 - to the nearest tenth
= 12.7ft

Answer:
B. AB/DE = AC/DF
Step-by-step explanation:
When triangles are similar, corresponding sides have the same ratio. We are told that ∆ABC ~ ∆DEF. This means that corresponding sides are ...
AB : DE
BC : EF
AC : DF
Any pair of these ratios can be used to write the proportion. Each proportion can be written in 4 different ways. The answer choices show that AB and DE are involved in the proportion we want, so we can have any of ...
AB/DE = BC/EF
AB/DE = AC/DF . . . . . . matches choice B
AB/AC = DE/DF

Additional comment
When we say a proportion can be written 4 ways, we mean all of these versions of a proportion are fully equivalent:

Answer:
x = 4 and y = -6
Step-by-step explanation:
Solve by elimination by multiplying the first equation by -2:
-8x - 6y = 4
8x + 3y = 14
Add them together and solve for y:
-3y = 18
y = -6
Plug in -6 as y into one of the equations and solve for x:
8x + 3y = 14
8x + 3(-6) = 14
8x - 18 = 14
8x = 32
x = 4
So, the solution is x = 4 and y = -6
Answer:
x = 4
y = -6
Step-by-step explanation:
4x + 3y = -2
8x + 3y = 14
Multiply the second equation by -1
4x + 3y = -2
-8x - 3y = -14
--------------------------
-4x = -16
Divide by -4
-4x/-4 = -16/-4
x = 4
4x+3y = -2
4*4 +3y = -2
16 +3y = -2
3y = -2-16
3y = -18
y = -6
Find the solution set of this inequality. Enter your answer in interval notation using grouping symbols. -2x+5<3
Step-by-step explanation:
On solving ,
=> -2x +5 < 3
=> -2x < 3 -5
=> -2x < -2
=> x < -2/-2
=> x < 1
Hence x can have all values less than 1 ,
Therefore ,
=> x € ( -∞ , 1 )
Find the sum of the first 41 terms of the following series, to the nearest integer. 4, 12,20,...
Answer:
Sum of the first 41 terms = 6724
Step-by-step explanation:
[tex]a_{41} = a_1 + (n - 1 )d = 4 + (41 - 1) \times 8= 4 + 40 \times 8 = 324\\\\S_n = \frac{n}{2}(a_1 + a_n)\\\\s_{41} = \frac{41}{2} (4 + 324) = \frac{41}{2} \times 328 = 41 \times 164 = 6724[/tex]
The sum of the first 41 terms of the following series, to the nearest integer, is 6724.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Given:
An arithmetic sequence,
4, 12,20,...
The common difference d,
d = 20 - 12 = 8.
To find the sum of the first 41 terms:
We will find the 41st term.
Remember that,
aₙ= a₁ + (n-1)d
a₄₁ = 4 + (40)8
= 324
The sum of the first 41 terms,
Sₙ = (41/2)(4 + 324) = 6724.
Therefore, the sum is 6724.

Find ordered pairs for y=4x+2
Answer:
(1,6) (2,10) (3,14) etc.
Step-by-step explanation:
You can have infinite number of ordered pairs for this because all you have to do is plug in the x and solve for y. And then you ordered pair is like (x,y) so if you plug in 1 for x, you do y=4*1+2 and that equals 6. So for the x you used 1 and y equaled 6 so an ordered pair can be (1,6) and so on.

Answer:
[tex]x^{\circ}+105^{\circ}=180^{\circ},\\x^{\circ}=z^{\circ},\\180^{\circ}-z^{\circ}=y^{\circ}[/tex]
Step-by-step explanation:
Statement 1:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 2:
True - These two angles are vertical angles (opposite to each other at intersection of two lines). All vertical angles are equal.
Statement 3:
False - These two angles are vertical and therefore are equal. Thus, they cannot have a difference of 105.
Statement 4:
False - Two of these angles form one side of a line which is equal to 180 degrees. Since the third angle is greater than zero, they cannot all add up to 180 degrees.
Statement 5:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 6:
False - These two angles are supplementary (add up to 180 degrees) because they form one side of a line and therefore cannot be equal to 105.
Answer and Step-by-step explanation:
The answers are:
x + 105 = 180 (Supplementary angles = 180 degrees)
x = z (Vertical angles are congruent)
180 - z = y (Supplementary angles = 180 degrees)
