Answer:
The length is 600 ft
Step-by-step explanation:
We can solve this by applying the Pythagorean theorem
a^2 + b^2 = c^2
The hypotenuse (diagonal path) is 750
750 represents c, 750^2 is 562500
We also know the width (one side of the triangle)
450 can represent a, 450^2 is 202500
202500 + b^2= 562500
We can subtract 202500 on both sides to isolate the b^2
b^2= 360000
Square root both sides of the equation
B= 600
The length is 600 ft
Answer:
the total number of shingles is 3060
Step-by-step explanation:
Please have a look at the attached photo.
We need to find the total are of the roof.
The are of the trapezoid is:
- A = 1/2 (base 1 + base 2) height
= 1/2 (20+30)*15
= 375 
The are of the triangle:
= 1/2(1.5*10)
= 7.5
=> We need to find the total are of the roof is:
The are of the 2 trapezoids + The are of the 2 triangles
= 375 *2 + 7.5 *2
= 765
Given in the question that, the shingles are 1 foot by 1 foot, but they overlap by 0.75 square foot so the usable area of the shingle is only 0.25
So the total number of shingles is:
765 / 0.25
= 3060
Answer:
x = 20
Step-by-step explanation:
the angles shown are supplementary
supplementary angles add up to 180°
hence, 5x - 7 + 3x + 27 = 180
==> combine like terms
8x + 20 = 180
==> subtract 20 from both sides
8x = 160
==> divide both sides by 8
x = 20
