112. if k is a positive integer, then for every value of k, the sum of the k smallest distinct odd positive integers is equal to which of the following? f. k g. 2k h. 2k - 1 j. k^2 k. 2k^2 justify your answer, me understand! you!

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
