Question

How do i know the function in solving the missing sides of a right triangle ?

Answer 1

missing side of triangle can be find out using pythagoras theorem as
\[perpendicular ^{2}+ base ^{2 } = hypotenous ^{2}\]

Answer 2

If you are given the measure of an angle and one side you use the trigonometrical functions sine, cosine or tangent.

Answer 3

sine = opposite / hypotenuse
cosine = adjacent/hypotenuse
tangent = opposite/adjacent
