Trying to find the missing measurements for a triangle. you have to find x one corner is 60 degrees. the other is 40 degrees and the other corner says x+92.

To solve this problem you must follow the proccedure below:

 1. It is important to know that the sum of the interior angles of a triangle is 180 degrees. You have that one corner is 60 degrees the other is 40 degrees and the other corner x+92. Then, you have:

 60+40+(x+92)=180

 2. Now, you must clear the variable "x", as below:

 60+40+(x+92)=180
 192+x=180
 x=180-192
 x=-12 

 3. The other corner is:

 =x+92
 =-12+92
 =80°
