Question

In triangle ABC, c is the hypotenuse, theta=25 degrees, and b=3. Find the length of c.

Answer 1

3.31 is the answer

We can use the cosine to solve this:

cosine = Adjacent/Hypotenuse

cosine (25 degrees) = 3/Hypotenuse

hypotenuse*cosine (25 degrees) = 3

hypotenuse = 3/cosine (25 degrees)

hypotenuse = 3.310133...
