Question

The sum of two opposite angles of a quaderilateral is 260º. The other two angles are equal. Find the measureof each of the equal angles.​

Answer 1

Given,

(i) Sum of two other angles of quadrilateral = 260°

(ii) The other two remaining angles are equal.

To Find : Measurement of equal angles

Solution:

Let the equal remaining angles be 'x+x'

We know that sum of all angles of quadrilateral = 360°

=>260°+x+x = 360°

=> 2x = 360°-260°

=> 2x = 100°

=> x = 50°
