You focus your camera on a circular fountain. Your camera is at the vertex of the angles formed by tangents to the fountain. You estimate that this angle is 40°. Which of the following is the measure of the arc of the circular basin of the fountain that will be in the photograph? 80° 140° 160° 220°

answer: this is not a question

step-by-step explanation: this is a answer

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

well, if it's triangular garden, the triangle could represent the garden.
