A. What is the value of x? show your work

B. what is the measure of angle ? Show your work

C. what is the measure of angle C? show your work

Answer:

x=13

m∠A = 46°     m∠B = m∠C = 67°

Step-by-step explanation:

ΔABC : isosceles    

vertex ∠A = 4x -6

∠B = ∠C = 5x + 2

∠A + ∠B + ∠C = 180° = (4x -6) + 2 * (5x + 2) = 14x - 2

14x = 182       x = 13

∠A = 46°     ∠B = ∠C = 67°
