The probability for success of an event is p(a), and the probability of success of a second event is p(b). what is the probability of both events occurring, in that order?
a. p(a + b)
b. p(a) • p(b)
c. p(a) + p(b)
d. p(a x b)

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
