Question

What is the letter x?
I'm pretty sure y= 186.1 but I can't figure out what x is.

Answer 1

`y = (350)/(tan(28^(o))) = 658.3`

You probably did 350*tan(28) instead which gave the wrong value of y.


`x = (350)/(sin(28^(o))) = 745.5`

You can verify this answer by testing if the 3 values form a pythogorean triplet.


`350^(2) + 658.3^(2) = 555858.89`


`745.5^(2) = 555770.25`

Which gives an error ~0.1%, consistent with our 4 s.f. rounding above.
