1)suppose that T varies inversely as U^2 and T=5 when U=2. what is the constant. 2) suppose that T varies inversely as U^2 and T=5 when U=2. write the law of variation.
3) suppose that T varies inversely as U^2 and T=5 when U=2. Use the law of variation to determine the value of T if U is 0.5

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
