Question

The m∠A is 45 degrees. Find the m∠B.

A) 45 degrees

B) 50 degrees

C) 90 degrees

D) 125 degrees

Answer 1

A) 45°

Explanation:

∠B is a vertical angle to ∠A so there for their measurements are equivalent.

Answer 2

The correct option is A) 45 degrees

Explanation:

Consider the provided figure.

Two angles are said to be vertical angles if each of the pairs of opposite angles made by two intersecting lines.

The vertical angles are always equal.

Here A and B are the vertical angles. Thus the m∠A = m∠B

It is given that m∠A = 45°

Thus the m∠B = 45°

Hence, the correct option is A) 45 degrees
