Geometry problem
write an equation and solve x

Well, all the angles of a triangle are equal to 180.

First, we can find what the angle in the corner is because we know the outside angle.

180-111= 69

So,

(x-5)+3x+69= 180

We can solve it now.

Subtract both sides by 69.

(x-5)+3x= 111

Add five to the other side.

x+3x= 116

4x= 116

Divide both sides by 4.

x= 29

Plug those into the equations for the angles.

3(29)= 87
(87-5)= 82

87,82,69 are the measures of the angle.

I hope this helps!
