calculate sides of the right triangle if I know 1 side and all the angles
I'm not sure how to do this with only 1 side given, but I have a right triangle with a 30 degree angle and an unmarked angle. One side is 4 and the other two are x any y.
How do I find the values of x and y?
I think the hypotenuse is x adjacent is y and 4 is opposite.
