Answer:
Number of 45° angles = 1
Number of 90° angles = 1
Number of 135° angles = 3
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
