You can put this solution on YOUR website! the second angle of a triangle is two times as large as the first. The third angle is 15 degress less than the sum of the other two angles.Find the measure of the first angle
let first angle be x
the second angle will be 2x
third angle = 2x+x -15 = 3x-15
.
x+2x+3x-15=180
6x=195
x= 32.5 degrees
