Which graph represents the function h (x) = 2 sine (x + StartFraction pi Over 2 EndFraction) minus 1?

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

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

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