Answer: X x (X^2-5)
Step-by-step explanation:
Note that a triangle = 180 degrees, and that a square inside the triangle located in a corner means a right angle or 90 degrees.
The sum of the exterior angle is the addition of the two isolated interior angles:
90 + 53 = u
u = 143
The sum of a straight line is 180 degrees. Subtract 180 with 143
180 - 143 = 37
The measure of the missing interior angle is <u>37 degrees</u>

Answer:
simplified: −4y+4z+49
Step-by-step explanation:
=4z+−7y+2+2y+y+62+−15
Combine Like Terms:
=4z+−7y+2+2y+y+62+−15
=(−7y+2y+y)+(4z)+(2+62+−15)
=−4y+4z+49
