You want to make a rectangular garden. You want the length to be twice as long as the width. You have 180 feet of fence to put around the garden. What will be the dimensions (length and width) of the garden when you are finished? length:
width:

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

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
