I need help. Ive been on the test for a while

48

Step-by-step explanation:

its the only one that makes sense, if not, its still 42

A. 42°

Step-by-step explanation:

If angle 3 measures 42°, then angle 2 will also measure 42° because angles 2 and 3 are vertical angles. Vertical angles are angles that are opposite each other on the transversal.

I hope this helped! :)

21/58.

hope to be marked brainliest

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
