Lin Ying got 10 more red envelopes than her cousin Lin Ping. If Lin Ying got a total of 28 red envelops, write an equation could be use to find the number of red envelopes Lin Ping got. Solve the equation.

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°
