Question 891982: Can somebody please help me with this question? Triangle PSR has a right angle at P. The length of side PR is 8.4mm, and the length of side PS is 10.40mm. Draw triangle PRS, and find angle PSR, giving your answer correct to the nearest degree.
I know, that I have to use Pythagoras formula to find RS.
and answer is 13.37.
But now I'm not sure how to do the rest.

Triangle PSR has a right angle at P.
The length of side PR is 8.4mm, and the length of side PS is 10.40mm.
Draw triangle PRS, and find angle PSR, giving your answer correct to the nearest degree.
:
We can just use the tangent to find angle S, Tan = side opposite/side adjacent
tan (s) =
tan (s) = .8077
arctan .8077 = 38.92 ~ 39 degrees
