Question

If ∠a = 35°, what does ∠b equal?
∠b = ?°

Answer 1

Hello!

As you can see, b and a appear to form a right angle. This means they are complementary, and their angle measures add up to 90°. Le'ts subtract 35 from 90 to find b.

90-35=55

Therefore,
`\boxed {\angle b= 55 \circ}`.

I hope this helps!
