Answer: x = -12</h3>
=======================================================
Work Shown:
Let's label angle 2 as y, so y = x+132.
Also, let's add another variable z. We'll make z equal to the angle adjacent and supplementary to angle y. So y+z = 180
Solve for z to get
z = 180-y
z = 180-(x+132)
z = 180-x-132
z = 48-x
This angle z is added to the 90 degree angle to get the measure of the exterior angle 150 degrees. This is through the remote interior angle theorem.
So,
z+90 = 150
48-x+90 = 150
138-x = 150
-x = 150-138
-x = 12
x = -12
Answer:
51.575

Answer:
138
Step-by-step explanation:
Hey There!
So given that the opposite sides are equal to each other we know that angle RTU is equal to angle RTS so all we have to do is multiply 69 by 2
69x2=138 so angle STU = 138
