The 1st word problem.

Step-by-step explanation:

In the second word problem, the beginning elevation is -60 meters. The ending elevation is a forest with an elevation of 60 meters.

The question asks how much higher the elevation where Hayley goes camping than the elevation of desert shores.

Hayley's elevation=60 meters

Desert Shore's elevation = -60 meters.

60-(-60) = 60+60 = 120

The first word problem asks for the elevation where Hayley is going camping.

Hayley's elevation is Deserts shore's elevation + 60.

DSE= -60

-60+60=0

The first answer is correct.

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
