Question

measure of a two angles of a quadrilateral star 115 degree and 65 degree the remaining of two angles are equal find the measure of each equal angle​

Answer 1

Answer:

Measure of each equal angle = 90°

Step-by-step explanation:

Given two angles of the quadrilateral as 115° and 65°.

Let the other angles be x and x.

The sum of angles of a quadrilateral = 360°

ie, 115 + 65 + x + x = 360

180 + 2x = 360

2x = 360 - 180 = 180

x = 180/2 = 90°
