Answer:
The measure of other three angles is 70°.
Step-by-step explanation:
Sum of all the angles of the quadrilateral is 360°.
Means,
angle A + angle B + angle C + angle D = 360°
Also given that, three angles are equal and one of the angle is 150°
Say that angle A = angle B = angle C = x and angle D = 150°
Simply substitute the values,
→ angle A + angle B + angle C + angle D = 360°
→ x + x + x + 150° = 360°
→ 3x = 360° - 150°
→ 3x = 210°
→ x = 70°
Hence, angle A = angle B = angle C = 70°.
