Question

∠a and ∠b are complementary angles. ∠a measures 55 degrees
What is the measure of ∠b?

Answer 1

<b=35

Explanation:

Complementary means 90 degrees

and 90-55= 35 degrees

Answer 2

<b = 35

Explanation:

Complementary angles add to 90 degrees

a + b = 90

55 + b = 90

Subtract 55 from each side

55+b-55 = 90-55

b = 35
