Aramp makes an acute angle with respect to the horizontal. any two points along either edge of the ramp that are 12 feet apart differ in their horizontal positions by 11.5 feet. give the value of in degrees. round your answer to four decimal places

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°
