Two angles whose sides are opposite rays is called blank angles to compare angles with a common side

In this question , we have to fill the blank, and the question is

Two angles whose sides are opposite rays is called

Here it is given that there are two angles , and the sides of the angles are opposite rays. It means the angles are one after another, and such angles are known as adjacent angles .

So we have to put adjacent angles in the blank .

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
