Answer

Find the  cost of the meals before the tip.

To prove

As given

Emily takes her friend Darren out to eat for his birthday.

She pays a total of $45, which includes a 20% tip.

20% is written in the decimal form

= 0.20

Cost of the  tip = 0.20 × 45

                         = $ 9

Thus

Cost of the meals before the tip = Cost of the meal with tip - tip cost

                                                       = $45 - $9

                                                       = $ 36

Therefore the cost of the meals before the tip is $36 .

is there any photos or whatever?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
