Answer 1

look at the right side and imagine a right triangle. a^2+b^2=c^2 c=82+73.8 a=47. Solve for b. once you find b you can solve for the other side using the same idea.

Answer 2

47^2+b^2=155.8^2 24273.64-2209=b^2 b=square root of 22065.64
b=148.541711.

Answer 3

a^2+148.541711^2=174.8^2 a^2=30555.04-22064.63991 a^2=8490.400090
a= square root of 8490.400090 a=92.14.3367

Answer 4

now 92.143367-47=45.143367 92.143367-45.143367=47

Answer 5

looks like it might be B. I'd check my work though... its been awhile.
