Step-by-step explanation:
when sum of two angle is 90° we say it as complementary angle.
3a - 15 + a - 10 = 90
4a - 25 = 90
4a = 90 + 25
4a = 115
a = 115/4
a = 28.75
therefore the angles are
3a - 15 = 3(28.75) - 15 = 86.25 - 15 = 71.25°
a - 10 = 28.75 - 10 = 18.75
verification
71.25 + 18.75 = 90
Hope you get your answer
