The table shows the number of boys and girls who have come to the playground.

outcome boys girls
frequency 35 40

what is the experimental probability that the next person who comes to the playground will be a girl?

a.8/15

b.1/2

c.7/15

d.2/5

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
