Answer:
x=54
Step-by-step explanation:
since the angle is 90°, simply subtract 90 by 43 to get 47. However, in order for the angle above to equal 47, add 7 to the answer to get 54.
to check the answer, plug in x.
if it works properly, 54-7 should equal 47 and 43+47 should be equal to 90.
I hope this helps you!
