3. Solve for x. Round to the nearest tenth.
14
х
49°

So for this triangle you are going to use Cos, which is adjacent/hypotenuse.
In this case x is your hypotenuse.

So your equation is going to be Cos(49)= 14/x.
So in order to get x, you are going to have to multiply x by each side. So:

x • Cos(49)= 14/x • x.
Multiplying x and x is going to cancel each other out so your new equation is going to be:

xCos(49)=14.

Now we are going to divide each side by Cos(49). Dividing Cos(49) by itself, will cancel itself out, so then your new equation will be:

x = 14/Cos(49)

Now you are going to put that into your calculator and your answer will be

x = 9.18.
