Find the percent of change. Round to the nearest tenth of a percent if necessary. 57 people to 65 people. About___ % increase.

  14.0% increase

Step-by-step explanation:

One formula you can use for this is ...

  percent change = ((new value)/(old value) -1) × 100%

  = (65/57 -1) × 100%

  ≈ 0.1403 × 100%

  ≈ 14.0% . . . . . . the positive sign indicates an increase

you would need to know all the numbers that are on there

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
