Given :

A square of side 18 cm.

To Find :

Angle V on the square.

Solution :

This problem can be done easily without using pen and paper but we need to know the property of diagonal of square given below :

The diagonals of the square bisect each other at 90°.

This will hold true for any right angle triangle.

Therefore, the angle V on the square is 90°.

Answer:

See Explanation

Step-by-step explanation:

According to the Question,

1). find the value of x and y. (Please Find Diagram in the attachment)

⇒ Now, Because of the “1-1 pitch”, the triangle you see with x and y is an isosceles right triangle in Diagram, with hypotenuse 24.

⇒ That means x and y are equal (x=y) and using the 45° , 45° , 90° triangle ratio,

And, By Pythagoras Theorem We get

x² + x² = 24²

2x² = 576

x² = 288 ⇔ √288 ⇒ x=12√2 & y=12√2

2). Find the Total area of the roofing (Please Find Diagram in the attachment)

⇒ Now, The total area of the roof is the sum of the two isosceles right triangles on each side of the roof, plus the two rectangles.

⇒ Total Area = 2×{1/2× 12√2 × 12√2 × Sin90°} + 2×{35×12√2}

⇒ Total Area = 288 + 1187.93

⇒ Total Area = 1475.93 Unit²

Step-by-step explanation: You divide 4.68 by 9 for the unit price

Answer:

c is the same angle as a

b and d are the same as the other

and together the are what's left from 360° after a and c got their share

so

360 -98 -98 = b + d

makes

164 = b + d

since they are of equal value, just decide 164 by 2 and you got b and d at once

pls brainliest

Answer:

Vertical Angles: a and c , d and b

m<b= 82⁰ , m<c=98⁰ , m<d=82⁰

Adjacent Angles: a and b , b and c , c and d ,d and a

Answer: t=-3h+25

Step-by-step explanation:

t=-3h+25

25 degrees is a constant-- it never changes, no matter how many hours goes by. So, you don't multiply a variable with it.

The temperature drops every 3 hours-- this is not constant, since it's dependent on the number of hours that passes. So, use a variable here. Since the temperature drops every three hours, it's -3, and not 3.

Answer:

[tex]t=-3h+25[/tex]

Step-by-step explanation:

If we know that when [tex]h=0[/tex], [tex]t=25[/tex], then we can use a direct proportion equation ([tex]x=ky[/tex]). The temperature decreases every hour by 3 degrees. However, we know that before any temperature drop, the temperature was 25 degrees. All together, this gives us [tex]t=-3h+25[/tex], where [tex]-3h[/tex] is the temperature drop each hour, and [tex]25[/tex] is the starting temperature. Hope that explained things :)

Answer:

221.87 feet

Step-by-step explanation:

Given that,

A 525 ft cable runs from the top of an antenna to the ground.

The angle of elevation made by the ground to the top of an antena 25°

We need to find the height of the antenna.

Using trigonometry,

Hypotenuse, H = 525 ft

θ = 25°

So,

[tex]\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft[/tex]

So, the height of the antenna is equal to 221.87 feet.

Answer:

y = x

Step-by-step explanation:

i took two points which are very close to the trend line - (3,3) and (5,5) - to get the slope

the slope is 2/2 or 1 and the y-intercept is zero

this means the trend line is 'y = x'

Answer: The value of x can be either 5 or 10.

Step-by-step explanation:

We are given:

Total profit, P = $5600

The given equation follows:

⇒ P = 600 + 1500x - 100x²

Putting value of P in above equation, we get:

⇒ -100x² + 1500x + 600 = 5600

⇒ -100x² + 1500x - 5000 = 0

⇒ 100x² - 1500x + 5000 = 0

Solving this equation by middle term split, we get:

⇒ 100(x² - 15x + 50) = 0

⇒ (x² - 10x - 5x + 50) = 0

⇒ x(x - 10) - 5(x -10) = 0

⇒ (x - 10)(x - 5) = 0

⇒ x = 10, 5

Hence, the value of x can be either 5 or 10.

Answer:

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

4 + 3x + 3x + 14 + 90 = 180 , simplify left side

108 + 6x = 180 ( subtract 108 from both sides )

6x = 72 ( divide both sides by 6 )

x = 12

Then

∠ A = 4 + 3x = 4 + 3(12) = 4 + 36 = 40° → A

Answer:

Step-by-step explanation:

PQ = q-p

PQ = q-p, therefore PS = (2/3)(q-p)

OS = p + (2/3)(q-p) = (2q+p)/3

OR = q + p/2

Answer:

d

Step-by-step explanation:

We know that diagonals bisect angles of a rhombus, meaning that they split the angles of two equal parts, that opposite angles are equal, and that the angles of a quadrilateral, such as a rhombus, add up to 360 degrees.

Looking at the drawing I uploaded, and taking into account that diagonals bisect angles of a rhombus, we can say that angle x = y and z = 5x-18

Next, given that opposite angles are equal, we can say that angle B = angle D and angle A = angle C. Therefore,

A+B+C+D= 360 (as the angles of a quadrilateral add up to 360)

A + B + A + B = 360 (plugging in A for C and B for D)

2 ( A + B) = 360

A + B = 180

x + y + z + 5x - 18 = 180 (plugging x+y in for A, and z+5x-18 in for B, as x and y make up A and z and 5x-18 make up B)

x+x+5x-18+5x-18 = 180 (because x=y and z=5x-18)

2(x+5x-18) = 180

divide both sides by 2

x+5x-18=90

6x-18=90

add 18 to both sides

6x=108

divide both sides by 6

x = 18

B)
