So if you have x as one of the angles … WebTo solve this problem, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We can set up two equations based on the given information: m²A + m²B + m²C = 180 (Equation 1) m²A = x + 40₁. m²B = 3x - 10 = x + 15 . Substituting the values of m²A and m²B into Equation 1, we get: x + 40₁ + x + 15 + m²C = 180
