Answer:
37
Step-by-step explanation:
This is a vertical angle, meaning 74 and 2x would be equivalent to each other. So we have to make 2x equal to 74. We set up an equation, 2x = 74. Divide 2 for both sides; 74 divided by 2 = 37; 2x divided by 2 (2 cancels out, leaving x alone). Therefore, x = 37.
To check, substitute x with 37. 37 times 2 is 74, and since the left is 74 the right also have to be 74.
