Em um triângulo ABC, é traçado a bissetriz AD relativa ao ângulo interno do vértice A. Se AC mede 16cm, CD mede 8cm e BD mede 12cm, portanto, o segmento AB mede

answer: sorry

step-by-step explanation: can you tell me pls how to find the rational of two integers

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
