Question Help
Challenge A cell phone plan costs $22.90 per month for 500 minutes of talk time. It costs an
additional $0.06 per minute for each minute over 500 minutes. To get e-mail access, it costs 30% of
the price for 500 minutes of talk time. Your bill, which includes e-mail, is the same each month for 5
months. The total cost for all 5 months is $175.25. Write and solve an equation to find the number of
minutes of talk time you use each month.

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°
