| Now that you know the length of the line CB and the length of AB, you can use the tangent ratio to find out < ACB. | |
 | |  |
|
 |
| | |
| tanC should equal 1/ the square root of 2. | |
| | |
|
|
|
|
|
|
|
| | |
| You should then inverse the tan, and plug in 1/the square root of 2. | |
| | |
|
|
| | |
| After you do so, you'll get < C to be 35 degrees. | |
