A number cube has faces numbered 1 to 6. What is true about rolling the number cube one time? Select three options. S = {1, 2, 3, 4, 5, 6} If A is a subset of S, A could be {0, 1, 2}. If A is a subset of S, A could be {5, 6}. If a subset A represents the complement of rolling a 5, then A = {1, 2, 3, 4, 6}. If a subset A represents the complement of rolling an even number, then A = {1, 3}.

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
