second one, the equal angles are each 80 degrees

Mark me brainliest...:)

Answer 2

Answer:

8. measure of each angle is 90°

9. the measure of other three angle is 80°

explanation is given below

Step-by-step explanation:

8. we know that angle sum property of quadrilateral=360

let the measure of angle be x

therefore, x+x+x+x = 360

4x = 360

x= 360/4

x= 90°

9. we know that angle sum property of quadrilateral=360

let the measure of other three angle be x

therefore, 120+x+x+x= 360

120+3x= 360

3x= 360-120

3x = 240

x= 240/3

= 80°

therefore, measure of other three angle is 80°

hope this will help u
