Question

Find the angles A and B of the parallelogram ABCD if

A = 4x - 15 and B = 5x - 3​

1) 73, 107
2) 80, 100
3) 75, 105​

Answer 1

Answer:

x is12 so put value and solve it.

Answer 2

Answer:

73,107

Step-by-step explanation:

Sum of to angles of a quadrilateral is 180

4x-15+5x-3=180

9x-18 = 180

9x= 180+18=198

x=198/9

x=22

And therefore making x=22 for above 4x-15 and 5x-3 we will get 73 and 107
