Question

The m∠A is 45 degrees. Find the m∠B.

Answer 1

Answer:

The correct option is A)  45 degrees

Step-by-step 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

Answer 2

Answer:

A) 45°

Step-by-step explanation:

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