I believe that the answer should be 10,-4
Two angles are complementary when they add up to 90° ⇒
∠A + ∠B = 90°
3x + 5 + 2x - 15 = 90
5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100/5
x = 20
<span>m∠A = 3x + 5 = 3*20 + 5 = 60 + 5 = 65</span>°<span>
</span><span>m∠B = 2x - 15 = 2*20 - 15 = 40 - 15 = 25</span>°<span>
