Answer 1

15

Explanation:

We have the hypotenuse and adjacent values of the sides in the triangle provided, therefore we will be using cosine.

`cos(21.3)=(14)/(x)`

Multiply both sides by x:

`xcos(21.3)=14`

Divide both sides by cos(21.3):

`x=(14)/(cos(21.3))`

Solve using calculator:

15.0264
