Question #653d5

Answer 1

Change cotangent to sine and cosine ...

Explanation:

`cot50= cos50/sin50=x/2`

Next, use cross multiplication ...

`2cos50=xsin50`

Finally, solve for x ...

`x=(2cos50)/sin50~~1.6782`

Note: Since `50^o` is not a standard value on the unit circle , use your calculator to find the value of `sin50` and `cos50`

hope that helped
