Question

What is the value of x? 20,35,60or70

Answer 1

You are right it is 20.

Hope this helps.

Answer 2

x=20

Explanation:

∠TRS and ∠VRW are vertical angles, so the measure of the angles will be the same.

First, set the two values equal to each other: x+40=3x

Then, subtract x from both sides to isolate x: 40=2x

Finally, divide both sides by 2 to find the value of x which is 20
