Smalltown, inc has a holding tank 96" deep. Each day the water level in the tank is lowered .75" when the company supplies water to it's nearby factory. How long will it take for the water to reach a height of 91"?

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
