Question

Sarah is building a chair for her front porch. She cuts each leg so that they form a 45° angle with the base
of the seat of the chair as shown in the diagram below.

Pls I rlly need help.

Answer 1

Answer:

C. 135°

Step-by-step explanation:

The last angle in the top triangle is 90°

The top angle in the bottom triangle is also 90° because they are vertical angles.

The other two in the bottom are also 45° because they and the top 45° angles are alternate interior angles, which means they are equal

180 - 45 = 135°
