Will be giving out brainliest to whoever can answer this first

So we know that all triangles equal 180 degrees, basically the equation will look like this

(7x-11) + (2x-3) + (5x-2) = 180

So first we need to collect like terms

7x + 2x + 5x -11 - 3 - 2 = 180
= 14x -16 = 180

Then we need to move the constant to the right

14x = 180 + 16

Then add

14x = 196

Then divide both sides

The answer is 14 :)
