F=gmm/r^2 solve for g
can anybody ?

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

This is my question~~ ( r ^ 4 - 2r ^ 3 - 23 r ^ 2 - 4r - 32)÷(r+4) ~~ i must use long division to solve it : / i was wondering if anyone world like to solve it. and if so, share step-by-step explanations! you! ❤
