The sum of all the angles in a triangle is 180°.

(12x + 1) + 58° + 73° = 180°

12x + 132° = 180°

12x = 180° - 132°

x = 48°/12

x = 4°

A triangle equals 180° so set up the equation as
58+73+12x+1=180
132+12x=180 (I got 132 by adding 58,73,1)
Subtract 132 from both sides
You should get 12x=48
Divide both sides by 12
X=4
