Question

Select the correct answer from each drop-down menu.АBDF/CIn the figure, angle A measures 45° and angle E measures 15º.The measurement of angle C isThe measurement of angle D isO

Answer 1

Step 1

Using the law that the sum of angles in a triangle = 180°

Angle c = 180 - angle A - 90 = 180 - 45 - 90= 45°

Angle F = 180 - 45 = 135° ( sum of angles on a straight line)

Angle D = 180 - angle F - angle E = 180 - 135 -15 = 30°
