Find the measurement of angle 2

40 degrees

Step-by-step explanation:

the bottom right triangles missing angle is 80 and that reflects onto the top left triangle. You then do (60+80)-180 because all angles must equal 180 in triangles. the answer to that equation is 40 degrees.

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
