Question

The opposite angle of allgram are 2x+10 and 3x-20 find the angle

Answer 1

To find x

=> (2x-10) + (3x-20) = 180

=> 2x-10+3x-20 = 180

=> 5x-30 = 180

=> 5x = 180+30

=> 5x = 210

=> x = 210/5

=> x = 42

now x is 42 so 2*42-10= 74(angle 1)

3*42-20=106(angle 2)

Check- 106+74=180

HERE IS YOUR ANSWER!! hope it helps..
