Question

The measures of two angles of a quadrilateral is 115° and 45° and other two angles are equal measure of each of the equal angle

Answer 1

sum of four angles of quadrilateral=360°

115+45+2a=360°

160°+2a=360°

2a=360-160

2a=200

a=100°

other two angles measures equal

Answer 2

Given that,

Given that,

Angles are 115 and 45

And remaining two angles are equal..

Let's assume those angles as 'x'

We know that,

Sum of all angles in a quadrilateral is 360°

115+45+x+x = 360

160 + 2x = 360

2x = 360-160

2x = 200

x = 200/2

x = 100

Hence , measure of remains two angles are 100°.
