two angles are supplementary if the sum of their measures is 180 degrees. the measure of the first angle is 54 degrees more than 3 times the second angle. find the measure of the first angle.

Question

hero · Answer

1st angle = 3x + 54
2nd Angle = x

1st angle + 2nd Angle = 180
3x + 54   +  x             = 180
4x + 54 = 180

anonymous · Answer

a 4.5degrees
b.148.5degrees
c31.5 degrees
d.175.5 degrees

anonymous · Answer

4x + 54 = 180
4x = 180 - 54
x = 126/4
x=31.5
so
c 31.5 degrees

hero · Answer

Says find the measure of the 1st angle. You found the measure of the 2nd angle.

anonymous · Answer

so 31.5 times 3

anonymous · Answer

so first angle will be 3*31.5+54 = 94.5 + 54 =148.5
so ans is b.
