Question

the two adjacent angles of quadrilateral are 75 degree and 125 degree the other two angles are equal find the measure of each of these equal angles​

Answer 1

Answer:the angles are each 80°

Step-by-step explanation:

Given: angles of quadrilateral

=125°and 75°, remaining two are equal

Find:equal angles

Proof: let x be the equal angles

So, sum of all angles of quadrilateral is 360°

So,

125°+75°+2x=360°

200°+2x=360°

2x=360°-200°

2x=160°

x=160°\2

x=80°
