Step-by-step explanation:

The ASA postulate of congruence says that two triangles are said to be congruent if two corresponding angles and the side in between are congruent.

When we look at  , it can be seen that segment AB is the included side in between ∠A and ∠B.

The only triangle that has a segment with measure 5 lies between two corresponding congruent angles is .

Hence, by ASA postulate

step-by-step explanation:

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
