Question

I need help asappppp​

Answer 1

∠1 = 40

Explanation:

So due to the alternate interior angles theorem, angle 1 and angle 2 equal each other so:

2x + 20 = 3x + 10

subtract 2x from both sides

20 = x + 10

subtract 10 from both sides

10 = x

Now input 10 into the equation

2(10) + 20

20 + 20

40
