Question

The sum of two angles of a quadrilateral is 100° and the other two angles are equal. What is the measure of each of these two angles? Pls answer fast

Answer 1

Answer:

measure of each of these angles is 130°.

Step-by-step explanation:

let all angles be a, b ,c and d.

a + b = 100°

a + b + c + d = 360° (sum of all angles of a quadrilateral is 360°)

100° + c + d = 360°

c + d = 260°

since c = d,

c + c = 260°

2c = 260°

c = 130°

c = d = 130°
