Question 326101: Using pythagoran theorem & using sine, here's the problem I'm stuck on.
side a= x, side b= unknown, side c = 3x in a right triangle, how do you find side b?
And then to find the sine of A & B of a right triangle. A is opposite side x and adjacent to unknown side. B is opposite unknown side and adjacent to side x. What are the angle measures of angle A and angle B?

Thanks for your help!
