What is the length of the major axis of the conic section shown below?

The equation of a elipse:

The length of the major axis is equal 2a if a > b or 2b if b > a.

We have

therefore the length of the major axis is equal 2 · 7 = 14.

answer: 12

step-by-step explanation:

because yes

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
