Question

Two angles of a quadrilateral measure 85° and 75° respectively. The other two angles are equal. find the measure of each of these equal angles.

Answer 1

Sum of the angles of a quadrilateral =360 degrees.
Let the other two angles be x.
So, x+x+85+75=360
2x+160=360
2x=360-160=200
x=200/2
x=100 degrees

Hence, Other two angles are 100degrees each.

Answer 2

Heya!
Here's Your Answer
________________________________
.Since,

It's A Quadrilateral,
All Angles Sum Up to Form 360°
Since,
2 Angles are equal & not known,
Let Those be 2x

Then,
85°+75°+2x=360°
160°+2x= 360°
2x=360-160°
2x=200°
X=200/2°
X=100°
Therefore,
Measure Of Each Of these Equal Angles Are
100°
