4) jayda is running around a track where 3 laps is 5 km. she runs 6 laps in 20 min. what is her speed in min per plzz i will give you 100 pointd

Answer 16.8

Step-by-step explanation:

there is 20 minutes for 1/3 of an hour so 1 hour and 20 minutes would be

4 unites of time

4.2x4=16.8

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°
