Question 145963: I know the length of all 3 sides of a right triangle, how do I find the values for the other 2 angles of the triangle? Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! You would have to apply trigonometry.
.
Depending on your labeling, you can use one of the following:
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
.
where x is the unknown angle
.
since you are looking for the angle, you will have to use these relationships:
x = arcsin(opposite/hypotenuse)
x = arccos(adjacent/hypotenuse)
x = arctan(opposite/adjacent)
.
