Measures of the angle of r, 31 s (x+4) t (3x+9)

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

The daily production of a company is modeled by the function p = -w^2 + 75w - 1200. the daily production, p, is dependent on the number of workers (w) present. if the break-even point is when p=0, what are the least and greatest number of workers the company must have present each day in order to break even? 50 points! will give brainliest!
