Question

What is x? how would i find the value of x?

Answer 1

We will use the definition of the cosine function of an angle as follows:

`cos(x)=(adjacentside)/(hypothenuse)=(2)/(5.7)`

Now, let's solve the latter equation for "x" using the inverse cosine:

`\cos^(-1)((2)/(5.7))=x`

The answer is: x=69
