Question

Determine the value of x

Answer 1

x = 10

Explanation:

Since these angles are vertical angles, we know that 40 = 3x + 10. Subtract 10 from both sides to get 30 = 3x. Divide both sides by 3 to get x = 10.

Answer 2

x would be 10

Explanation:

angles across from each other are always equal so x would be 10 because 3 times 10 is 30 and then add the other 10 to get 40
