Haruto simplified the value below. csc(19pi/4)=sqrt2. Which statement explains whether Haruto is correct. A. Haruto is correct because the angle is coterminal with 3pi/4 and the reference angle is pi/4 B. Haruto is correct because the angle is coterminal with pi/4 which is also the reference angle. C. Haruto is not correct because the angle is coterminal with 3pi/4 and csc(3pi/4)=-1/sqrt2= -sqrt2/2 D. Haruto is not correct because the angle is coterminal with pi/4 and csc(pi/4)=1/sqrt2=sqrt2/2

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

do your own work and don"t cheat.

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
