Question

Each of two equal angles of a quadrilateral is of measure 80° and the other two angles are also equal What is the measure of each of these two angles?
Ans- 100°each

please send steps​

Answer 1

Answer

Let the two angle be x

Given two angle measure 80

Sum of angle in quadrilateral is 360°

80+80+x+x=360

160+2x-360

2x-360-160

2x=200

X=200/2

X=100°

Answer 2

Answer:

100°

Step-by-step explanation:

we know that the sum of all the angles of a quadrilateral is equal to 360 degree

The equation formed will be :

80 + 80 + x + x = 360°

160 + 2x = 360

2x = 200

x = 200/2

x = 100°
