Question 1111632: Angle θ is an acute angle in a right triangle.If m∠θ=31∘ and the side adjacent toθ has length 13, how long is the hypotenuse? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Both angles are acute in a right triangle, no need to mention that. Plus, it's 31º, which is acute.
----
cos(31) = 13/hypotenuse
