Answer:
x = 20
Step-by-step explanation:
the angles shown are supplementary
supplementary angles add up to 180°
hence, 5x - 7 + 3x + 27 = 180
==> combine like terms
8x + 20 = 180
==> subtract 20 from both sides
8x = 160
==> divide both sides by 8
x = 20
P = 8 + 10 + 8 + 10
P = 36

That's "5 to the negative seventh power," and is equal to
1 1
---------- = --------- . I would accept "1/(5^7)" as correct.
5^7 78125
