Answer:
35° is your answer.
Step-by-step explanation:
These are vertical angles. Set the two measurements equal to each other and solve for x.
3x - 4 = 2x + 9
Isolate the variable (x). Note the equal sign, what you do to one side you do to the other. Add 4 and subtract 2x from both sides.
3x (-2x) - 4 (+4) = 2x (-2x) + 9 (+4)
3x - 2x = 9 + 4
x = 13
Plug in 13 for x in one of the measurements given.
2x + 9
2(13) + 9
26 + 9
35
35° is your answer.
