Question

in the diagram the measure of angle one is 3X the measure of angle two is 12 X what is the measure of angle 4

Answer 1

144°

Explanation:

m<1 =3x

m< 2= 12x

1&2 are supplementary angles, so

3x+12x= 180

15x=180

x= 12°

measure of angle 4 equals the measure of angle 2

because they're head opposite angles

m<4= 144°
