tanØ = 1/8 = .125
Ø = 7.13 or appr 7°
in parallelogram , TRIG m<R 2x + 19 m<G = 4x - 17
in parallelogram , TRIG m<R 2x + 19 m<G = 4x - 17
what is m<t
The slope is 1/18 not 1/8. Also, the complete is:

tan(angle) = 1/18
to get the angle use the inverse tan function (tan^-1)
angle = tan^-1(1/18) ~= 3 degrees.
