Question

Which is the correct one???

Answer 1

Answer:

x=12    Hope this helps!!!

Step-by-step explanation:

Remember a straight line equals 180 and when you have the box the angle is 90 degrees. Try solving the equation 5x-22+4x+4+90=180.

5x-22+4x+4+90=180    (combine like terms)

9x+72=180         (subtract 72 from both sides)

9x=108               (divide 9 on both sides)

x=12                    

Answer 2

Answer:

52

Step-by-step explanation:

5x-22+4x+4 = 90

9x-18=90

9x=108

x=12

4*12+4

52
