Question

In ABCD parallelogram two adjacent angles are (x - 20°) and (x+10°) then x =​

Answer 1

Answer:

x = 95

Step-by-step explanation:

We know that the adjacent angles of a parallelogram are supplementary

So, (x-20) + (x+10) = 180

x - 20 + x + 10 = 180

2x - 10 = 180

2x = 190

x = 95

Answer 2

(x - 20°)+(x+10°)=180°   (consecutive interior angles.)

x-20+x+10 = 180

2x=180+10

2x=190

x=190/2

x=95
