Tamika’s father gave her $50 to start her savings account. She deposited $15 in the account each month that followed. Is the amount of money in Tamika’s savings account proportional to the number of months that have
passed since her father gave her the $50 to open the account? Use the graph below to help determine if the
relationship is proportional. Then choose the answer that explains your reasoning.

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
