Question

two angles of quadrilateral are 80 and 130 yhe other two sides are equal. find other two angles​

Answer 1

Answer:

Let the two equal angle of quadrilateral be x and x.

80+130+x+x=360

2x=360-210

2x=150

x=150/2

x=75

so,the two equal angle of quadrilateral is 75degree and 75 degree.

Answer 2

75

Step-by-step explanation:

let the angles be x

80+130+x+x=360

210+2x=360

2x=360-210

2x=150

x=150/2

x=75
