PLEASE help me solve this problem

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

Identify which functions are linear or non-linear. a. f(x) = x2 + 1 b. f(x) = 2x + 5 c. f(x) = x 2 + 3 d. f(x) = 3 x + 7 e. f(x) = 4x + 10 2 - 5

If the discriminant if a quadratic equation is 4 which statement describes the roots?
