-22 because -8+-9 is -17 plus 2 equals -15 plus -7 is -22
1,2,4belong on company sources and 3 should be on external information
let 2nd angle = x
then 1st angle = 2x-15
then you have 90 = x + 2x-15
2x +x = 3x
so now 90 = 3x-15
add 15 to each side
105=3x
x = 105/3 = 35
1st angle = 35 degrees
2nd angle = 2(35) - 15 = 70-15 = 65
