Question

A right triangle has legs e and fand hypotenuse h. The value of e = 10. The angle opposite legfis

35º. Which expression can be used to find the length of the hypotenuse?

Answer 1

`hyp=(10)/(cos(35^o))`

Explanation:

The trigonometric function that uses the value of the angle, the value of the adjacent side (e) and the hypotenuse is the cosine of the angle as shown below:

`cos(35^o)=(adj)/(hyp) =(10)/(hyp) \\hyp=(10)/(cos(35^o))`
