Question

The two angles of a quadrilateral are 82 and 78 .The other two angles are equal .Find the measure of each of these angles

Answer 1

Let the measure of the other two angles be x.

Sum of the interior angles of a quadrilateral :

(2n-4)×90°

=(2×4-4)×90°

=4×90°

=360°

The equation is :

82+78+x+x=360

=>160+2x=360

=>2x=360-160

=>2x=200

=>x=200/2

=>x=100

Therefore, each equal angle is 100°each (ans)
