Δ ABC is isosceles. If m∠A = 100°, m∠B = (12x + 4)°, and m∠C = (14x - 2)°, find x. A) 1 B) 3 C) 5 D) 7

valkas [14]

Since the sum of the angles of a triangle is 180 degrees, we simply have to add all the angles and equate it to 180 to solve for x. So:100 + 12x + 4 + 14x - 2 = 18026x = 78x = 3
So, x is equal to 3.
