For 1 hour of babysitting Felicity earn $9 .

Step-by-step explanation:

As given

Felicity babysat 2 hours each night for 10 nights.

Total number of hours Felicity did babysitting = 2 × 10

                                                                           = 20 hours

As given

she earned a total of $180 babysitting.

i.e  for 20 hours of babysitting Felicity earns $180.

Thus

20 hours = $180

For 1 hour.

1 hour = $ 9

Therefore for 1 hour of babysitting Felicity earn $9 .

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°
