19+Right+Triangle+Trig+(Side+Length)

Summary: Finding the lengths of sides on a right triangle is easy when you use Sine, Cosine, and Tangent also known as SOHCAHTOA. We use this when we are given an angle measure of a right triangle. To find a certain side length, you use either Sine, Cosine, or Tangent depending on which side is given and which side you need. By following the proper formula, you will be able to find the length you are looking for.

Sine = Opposite side/hypotenuse Cosine = Adjacent side/ hypotenuse Tangent = Opposite side/adjacent side

Problem #1 m<B = 52º b = 16 c = 20.3

Problem #2 m<A = 18º b = 8.3 c = 8.7

Problem #3 m<A = 24º a = 7.1 c = 17.5
