Answer:
x = 21º
Step-by-step explanation:
∆ ABC is isosceles therefor
Angles B and C are congruent
(180 - 18)/2 = 162/2 = 81º
------------------
∆ BCD is equilateral therefor all angles are 60º
---------------------------
x = = 81 - 60
x = 21º

Answer:
Since -15/16 does not equal -16/15, the statement is verified/true.
Step-by-step explanation:
Plug in the numbers for the variable:
-3/4 ÷ 4/5 =/ 4/5 ÷ -3/4
Copy dot flip:
-3/4 × 5/4 =/ 4/5 × -4/3
Multiply numerators and denominators separately:
-3 × 5 / 4 × 4 =/ 4 × -4 / 5 × 3
-15 / 16 =/ -16/15
-15/16 =/ -16/15
-15/16 does not equal -16/15.

Answer:
89*
Step-by-step explanation:
To find the value of m<1, you need to find the angle right next to it (the third interior angle that isn't labeled).
To find that angle (let's call it x), we have to use an equation.
Since a triangle has a sum of 180* for the interior angles in it, then we can use that to solve for x.
x + 53 + 36 = 180
x + 89 = 180
x = 91
Now to find m<1, we need to use the supplementary angles theorem.
Since m<1 and x are supplementary angles, the sum of those angles would be 180. Using this, we can create an equation.
x + m<1 = 180
91 + m<1 = 180
m<1 = 89
Hence, m<1 is 89*!
Hope this helped! <3
The width of a rectangle measures (3s+t) centimeters,and it’s length measures (3s-9t) centimeters. Which expression represents the perimeter,in centimeters of the rectangle ?
Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:Perimeter of the rectangle =(12s -16t)centimeters.
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+w)
Given that width of the rectangle=(3s+t)centimeters. and
Length of the rectangle=(3s-9t)centimeters.
Solving we have
Perimeter= 2(l+w)
Perimeter=2(3s+t +3s-9t)
Perimeter=2(3s+3s -9t+t)
Perimeter=2(6s-8t)
Perimeter=(12s -16t)centimeters.

determine the level in decibels of a sound that has an intensity I = 10^-6 watts/cm2
Answer:
The level in decibels is 100.
Step-by-step explanation:
The intensity level in decibels (β) can be found using the following equation:
[tex] \beta = 10log(\frac{I}{I_{0}}) [/tex]
Where:
I: is the intensity = 10⁻⁶ W/cm²
I₀: is the reference intensity = 10⁻¹² W/m²
First, we need to convert the unit of the given intensity from W/cm² to W/m².
[tex] I = 10^{-6} \frac{W}{cm^{2}}*\frac{(100 cm)^{2}}{1 m^{2}} = 10^{-2} W/m^{2} [/tex]
Hence, the level in decibels is:
[tex] \beta = 10log(\frac{10 ^{-2} W/m^{2}}{10^{-12} W/m^{2}}) = 100 dB [/tex]
Therefore, the level in decibels is 100.

The trapezoid is enlarged by a scale factor of 3, what is the area of the scaled copy?
Answer:
Step-by-step explanation:
After enlargement,
Parallel sides are: 6*3 = 18 cm & 10*3 = 30cm
Altitude = 5 *3 = 15 cm
Area =[ (sum of the length of parallel sides)*height] ÷2
[tex]= \frac{(18+30)*15}{2}\\= \frac{48*15}{2}\\\\= 24 *15\\\\= 360[/tex]
Answer:
360 cm²
Step-by-step explanation:
The area (A) of the trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ are the parallel bases
Here h = 5 , b₁ = 10, b₂ = 6 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (10 + 6) = 2.5 × 16 = 40 cm²
Enlarging by a scale factor of 3 means the area is increased by a factor
3² = 9
area of scaled copy = 9 × 40 cm² = 360 cm²

Find the first, fourth, and eighth terms of the sequence
A(n) = −2 ∙ 2x − 1
Answer:
1st term = -5
4th term = -17
8th term = -33
Step-by-step explanation:
1st term = -2 x (2 x 1) -1
= -2 x 2 - 1
= -4 - 1 = - 5
4th term = -2 x (2 x 2) -1
= -2 x 4 - 1
= -8 - 1 = - 9
8th term = -2 x (2 x 8) - 1
= -2 x 16 - 1
= -32 - 1 = - 33
