In a triangular cross section of a roof, the second angle is twice as large as the first.  The third angle is 20 degrees less than the first angle.  How large are the angles
Oct 6th, 2014

let the first be x

so the second angle will be 2x

the third angle will be x-20

x+2x+x-20=180

4x=180+20

x=200/4

x=50 degrees

2x=100 degrees

x-20=30 degrees
