Answer:
x = 1.5
Step-by-step explanation:
5x - 5 - 3x + 2 = 0
Combine like terms
2x - 3 = 0
Isolate variable x
Add 3 to both sides
2x = 3
Divide both sides by 2
x = 3 ÷ 2
x = 1.5
You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops
(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft
