Answer:
11.8° and 78.2°
Step-by-step explanation:
let the angles be x and x + 66.4
complementary angles sum to 90° , then
x + x + 66.4 = 90
2x + 66.4 = 90 ( subtract 66.4 from both sides )
2x = 23.6 ( divide both sides by 2 )
x = 11.8 and
x + 66.4 = 11.8 + 66.4 = 78.2
The 2 angles are 11.8° and 78.2°
