In triangle ABC, THE MEASURE OF ANGLE B IS 21, MORE THAN THREE TIMES THE MEASURE ANGLE A, THE MEASURE OF ANGLE C IS 54, MORE THAN THE MEASURE OF ANGLE A,FIND THE MEASURE OF EACH ANGLE
Let angle A=x. So, three angles are x, 3x+21, and x+54. So, x+3x+21+x+54=180. So, 5x= 180-75=105. So, x= 21. So, A= 21 degree, B= 84 degree and C= 75 degree
