Answer:
138
Step-by-step explanation:
Do the inverse. 69 2/3 multiplied by 3 is 138.
Y = mx + b. Use this equation for most linear functions. Enter the information that is given to you.

Multiply the -3 and 4 to get 12.

Now divide the -12 from both sides.

-12 cancels out on the right side and your left with

Now re-enter the info back into the formula.

Then you've got your formula
The vertical angles are congruent (or equal) so,
32 = 2x
2x = 32
2x/2 = 32/2 ..... dividing both sides by 2
x = 16 which is the answer
