Answer:
(C)
Step-by-step explanation:
X^2 -36 = 0 the ans is X=6 and x =-6 because 6^2=36
The line in the middle has a right angle, so the angle just above the Y would be 90 degrees.
The angle to the right of y is given as 48.
The three inside angles of a triangle need to equal 180.
So y = 180 - 90 - 48 = 42 degrees.
