What's the measurement of x?

Pls answer A.S.A.P

Option C, 36 degrees

Step-by-step explanation:

Step 1:  Make an Equation since 4x and x are supplementary, that means that they add up to 180 degrees.

4x + x = 180

Step 2:  Solve for x

4x + x = 180

5x / 5 = 180 / 5

x = 36

 Option C, 36 degrees

1 cup of flour for every 1 and 1/3 cup of milk
