Question

The measures of two angles of a quadrilateral are 15? and 45? and the other two angles are equal. find the measure of each of equal angles

Answer 1

Dear Student,
Let the measure of each equal angle = x °
15° + 45° + x ° +x° = 360°. { Sum of angles of a quadrilateral = 360°}
60° + 2x° = 360°
2x° = 360°- 60°
2x° = 300°
x° = 150°
The measure of each equal angle = x = 150° Ans.
