So it may be a long process, but the way i solved this problem was to first find the measure of one interior angle, then subtract that from 180 (supplementary angles) to get the measure of x.
HOW TO:
1) Find measure of ONE interior angle (keep in mind that, as labeled in the diagram, each interior angle is the same measure):note that n stands for the number of sides.
(n-2)180/n
(5-2)180/5
(3)180/5
540/5
108
So the measure of ONE interior angle is 108 degrees.
2) Now subtract 108 from 180 to get the measure of x.
180-108 = 72
Thus, the measure of x is 72 degrees.
Answer:
x= (y+2)/5
Step-by-step explanation:
Let f(x) = y
y = 5x -2
Adding 2 on both sides
y +2= 5x
Divinding by 5 in both sides
(y+2)/5 = x = f*(x)
Therefore,
f*() = (y+2)/5
.

Answer:
31/40
Step-by-step explanation:
Find a common denominator, I will use 80. So 7/8 will become 70/80, and 1/10 will become 8/80. Now just do the math, 70/80 - 8/80 = 62/80 or 31/40
