Answer:

B. 52°

Step-by-step explanation:

You need to add both equations and set them equal to 90 degrees because the other side is 90 degrees and the entire line must equal 180.

So...

[tex]5x-22+4x+4=90\\[/tex]

Combine like terms

[tex]5x+4x= 9x and -22+4= -18[/tex]

So:

[tex]9x-18=90\\[/tex]

Add 18 to both sides

[tex]9x=108\\[/tex]

Divide 9 on each side to get X=12.

Then you must plug in the 12

[tex](4(12)+4)\\(48+4)\\52[/tex]
