Answer:
Angle of A = 90 degree-62 degree =  28 degree. 
Step-by-step explanation:
tan (62) = opposite / adjacent = 10 / a ---> a = 10/tan (62) = 10/ 1.88 = 5.319
cos (62) = a/c --->c = a/cos (62) = 5.319 / 0.47  = 5.3 / 0.47  = 11.3 
or another way. 
sin (62) = 10 /c  ---> c = 10/ sin (62) = 10 / 0.88 = 11.3 
So Angle of A = 28 degree.
a = 5. 3
c =  11.3.

When you have a power to a fraction, you simply take it by the top and then by the bottm. 
So, split it into two: (2)^4 and (5)^4 
Solve: (2)^4=16
(5)^4=625
So the fraction is: 16/625
Check to see if it reduces: It doesn't. (Odd and even numbers that have no common multiples). 
Therefore, that's the answer.
