The angles of a triangle always sum to 180 degrees.

 

So, we now that x + x + 10 + 3x - 5 = 180

 

Which means: 5x +  5 = 180

 

Which makes 5x = 175

 

And x = 175/5 = 35 :D

The sum of the degrees in any triangle is 180 degrees

 

(x+10)+(3x-5)+x=180

 

5x+(10-5) = 180

 

5x+5=180

 

5x = 175

 

x=35
