Help me I hate math and this is bad it’s on my test on Monday

Plz help plz give me the answer

If sr is 4.5cm and tr is 3cm, what is the measure in degrees of angle s?

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
