Pat bought running shoes for $60. This was four dollars more than 2.5 times the cost of her old
shoes. How much were her old shoes?

$22.40

Step-by-step explanation:

Set up the equation like this: 2.5x + 4 = 60

Then solve for x.

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°
