Question

∠A and ∠B are complementary. If m∠B = 64° , what is the measure of ∠A?

26°
36°
11°
64°

Answer 1

Answer: 26

Explanation:

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). Then

∠A + ∠B = 90

∠A =90- ∠B

∠A = 26

Answer 2

The measure of
`\angle A`:

`\angle A = 26\textdegree`

Explanation:

Since both
`\angle A` and
`\angle B` are complementary (Which they both add up to 90°), and you want to find the measure of

Measure of
`\angle A`: unknown

Measure of
`\angle B`: 64°

Finding the measure of
`\angle A`:

`90 - 64 = 26`

`\angle A = 26\textdegree`

So, the measure for
`\angle A` is
`26\textdegree`.
