Question

If X = 14, find the value of the variable a. If your answer is not an integer, express it in simplest radical form.

Answer 1

Explanation:

First thing I would do is square the 14, and put it under the radical. Itll make the calculations a little bit easier.

14sqrt(2) = sqrt392

Use the definition of sine to find the value of a

sin(45) = opposite/hypotenuse = a/sqrt392

`sin(45)=(a)/(√(392) )`

a = 14
