Answer:
A = 125º
Step-by-step explanation:
Missing angle is the supplement of 157.5
180 - 157.5 = 22.5
----------------------------
Sum of angles in triangle is 180
22.5 + (-10x) + (-x + 20) = 180
Combine like terms
-11x + 42.5 = 180
Subtract 42.5 from both sides
-11x = 137.5
Divide both sides by -11
x = -12.5
---------------------------
A = -10(-12.5)
A = 125º

Average is the total of x divide by number of x.
Here, we have,
x = 55, 64, 60, 61
number of x = 4
Total of x = 55 + 64 + 60 + 61 = 240
So, the average is,
240 / 4 = 60
