Question

abcd is a cyclic quadrilateral if angle b = 81+x and angle d =89 find value of x

Answer 1

Hey!!!

We know opposite angles of a cyclic quadrilateral are supplementary this b + d = 180

=> 81 + x + 89 = 180

=> x = 180 - 170

=> x = 10

Hope this helps

Answer 2

81+x+89= 180
x=180-170
x=10
may this help u
