Answer:
Hello! So your answer would be 90 degrees!
Step-by-step explanation:
So the equation would be
x + 50 + 40 = 180.
50 + 40 = 90
180 - 90 = 90!
So basically y and x are both 90
First, add 29 on both sides.
42 - x is less than or equal to 0.
Next, add x on both sides.
42 is less than or equal to x.
Hence, the correct answer is (C).
It is called the ANGLE of the rotational symmetry:)
