Scalene triangle with 90, 75, abd 15 degree angles.
Shortest side is 5 inches
What are the other two side lengths?
--------------
It's a right triangle, so that makes it easier.
The short side is opposite the small angle, 15º, so 5 = hyp*sin(15)
hyp = 5/sin(15) = 19.3185...
------------
The tan(15) = 5/side 3, so the 3rd side is 5/tan(15)
Side 3 = 18.660...
As a check use Pythagoras:
So it's correct.
