Question

The angles of a cyclic quadrilateral ABCD in degrees are ∠A=2x, ∠B=(6y+10), ∠C=(2x+y) and ∠D= (x+10). Then measure of ∠C in degrees is

Answer 1

Step-by-step explanation:

A+C=18o° [ opposite angles of cyclic quad.]

2x+6y=17o°------(1)

Similarly

B+D=18o°

2x+y+x+1o=18o

3x+y=17o----(2)

by elimination method you can find value of x and y and put them in their value

Hope you will get your answer!!!
