Question

in triangle abc the measure of angle b is 36 more than three times the measure of angle a. the measure of angle c is 54 more than the measure of angle a. find the measure of each angle

Answer 1

b = 36 + 3a
c = 54 + a
a + b + c = 180
a + 36 + 3a + 54 + a = 180
5a = 180 - 90
5a = 90
a = 16
b = 36 + 3(16)
= 36 + 48
= 84
c = 54 + 16
= 70

Answer 2

a + (3 a + 36) + (a + 54) = 180
a = 18, b = 90, c = 72

Answer 3

yeah robtobey is right,....i make mistake in my work,...90 / 5 is 18 for the measure of a...
sorry,...applause for u rob...
