Answer:
5° and 85°
Explanation:
the sum of complementary angles is 90°
sum the 2 angles, equate to 90 and solve for x
x - 30 + 2x + 15 = 90
3x - 15 = 90 ( add 15 to both sides )
3x = 105 ( divide both sides by 3 )
x = 35
Then
x - 30 = 35 - 30 = 5
2x + 15 = 2(35) + 15 = 70 + 15 = 85
the 2 angles are 5° and 85°
