Question

each of two equal angles of a quadrilateral is of measure 80degree and the other two angles are also equal. What is the measure of each of these two angles? ​

Answer 1

Answer:

Step-by-step explanation:

Angle sum of quadrilateral is 360

So

Two angles are 80 each

And other two are equal(X)

360=80+80+X+X

360=160+2X

360-160=2X

200/2=X

100=X

Other two angles are 100 degree

Answer 2

Answer:

80°+80°+x+x=360°

160°+2x=360°

2x=360°- 160°

2x=200°

x=200/2

x=100°
