324 people went to an exhibit the first week. on the second week, 549 people went. what was the percent increase?

First find the difference between the two weeks:

549 - 324 = 225

Now divide the difference by the first week value:

225 / 324 = 0.694 x 100 = 69.4% ( round the answer as needed).

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
