Recall that two angles are complementary if the sum of their measures is 90°. Find the measures of two complementary angles if one angle is 15° more than four times the other angle

Answer 1

A = 15 +4B

A+B = 90

A = 90-B

90-B = 15+4B

5B = 75

B = 75/5= 15 degrees

A = 90-15 = 75 degrees

75 = 15(4)+15 = 60+15

Answer 2

Hi Tori B

15°

75°

Let one angle = x

The other angle = 4x + 15

x + (4x + 15) = 90

Just solve for x

Hope this helps.
