What does a break-even analysis tell a business planner?

A break-even analysis tells a business planner how much they need to sell monthly, quarterly, or annually in order to cover the business costs. This gives you a understanding of what you will need to sell in order to make a profit. Typically it would involve making a chart that shows your fixed costs, variable costs, and what the revenue is per unit of sales.

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°
