Question

Two angles of a quadrilateral are of measure 50 degree, and the other two angles are equal. What is the measure of each of these two angles​

Answer 1

Answer:

Let the angles of quadrilateral be

A, B, C & D

Let measure of angle A and B = 50°

And angle C = angle D

In a quadrilateral, sum of all 4 Angles = 360°

• A + B + C + D = 360°

• 50° + 50° + 2(angle C) = 360°

• 2(angle C) = 360° - 100°

• 2(angle C) = 260°

• angle C = 260/2

• angle C = 130°

Therefore,, angle C = angle D = 130°
