Question

Find the measure of angle BAC given the following:

Ray A C bisects angle B A D. The measure of angle B A C equals 3 x plus 4. The measure of angle C A D equals 4 x minus 8.
Triangle A B D is drawn with a ray inside. The endpoint of the ray is at angle A and the ray passes through point C which is on side B D. Ray A C bisects angle B A D. The measure of angle B A C equals 3 x + 4. The measure of angle C A D equals 4 x minus 8.

Answer 1

3x+4=4x-8
x=12

m<BAC=3x+4
3(12)+4
= 40
