Have you tried multiplying 5(3)+2(2)+1?
15 + 4 + 1 = 20 ?
Im sorry I'm not real good with math.
4 of 9
so 4/9 = 0.44444444444444444444444444444repeating
(sorry, not sure how to get bar notation for that)

Answer:
T = 60 degrees
Step-by-step explanation:
The dotted line is the height so it is a right angle
We are able to use trig functions since this is a right triangle
cos T = adj side / hyp
cos T = a/b
cos T = 8 sqrt(2) / 16 sqrt(2)
cos T = 1/2
Taking the inverse of each side
cos^-1 ( cosT) = cos^-1 ( 1/2)
T = 60 degrees
Answer:
-2 I believe. because the 1st exponent would make it 9, and then you'd remove 2
