Question 611355: The measure of the first angle of a triangle is 12 degrees more than the measure of the second. The measure of the third angle of the triangle is 4 less than twice the measure of the second. Find the measures of the angles of the triangle.
Please help can't seem to come up with an equation to solve. Answer by solver91311(24713) (Show Source):
Since both of the given conditions are referenced to the second angle, let represent the measure of the second angle. Then the measure of the first angle is and the measure of the third is
Add the three expressions for the three angles and set them equal to the number of degrees that represents the sum of the measures of the angles in all triangles.
Solve for then calculate and

My calculator said it, I believe it, that settles it
