the exterior angle equals the the sum of the two opposite interior angles
6x = x + 40 + 3x + 10
Triangle ABC is extended to point D Angle CAB =x+40 Angle ACB = 3x +10 angle CBD = 6x what is measure of angle CAB?
I can get angles inside triangle to equal 180 but when I check for the extended point it does not add up to straight line 180
