Answer:

Number of 45° angles = 1

Number of 90° angles = 1

Number of 135° angles = 3

Step-by-step explanation:

From the figure attached,

Angles in Figure D are,

Measure of angle A = 45°

Measure of angles B = 45° + 90° = 135°

Measure of angle C = 90° + 45° = 135°

Measure of angle D = 45° + 90° = 135°

Measure of angle E = 90°

Therefore, number of 45° angles = 1

Number of 90° angles = 1

Number of 135° angles = 3
