Explain why the speed limit on a highway is an example of a unit rate. Give another example.

These speed limits and price rates are known as unit rates because they give us the rate per unit -- in the speed limits, the unit is hours -- in the prices, the unit is pounds. ... The speed limit of 55 miles per hour is the same as the ratio 55 miles to 1 hour.

its an acute right triangle

step-by-step explanation:

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
