Finding the sides of a right triangle

This is my first post and I hope it is not too simple. How do you find the sides of a right triangle when you know the hypotenuse (48") and the three angles (90 a/b, 11.25 a/h, 78.75 b/h)? I need to find the lengths of a and b. Thank you for any assistance. Peace and God bless.

Re: Finding the sides of a right triangle

you can use basic trigonometric ratios

b=hcos78.75 and a=hsin78.75

What do you mean with hypotenuse (48''), the hypotenuse is a side, not an angle?

*"* can be used as a measure of length (inches)
