It took a submarine 20 seconds to drop 100 feet below sea level from the surface. Show by writing each number as an integer. Then set up a division expression and simplifying

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

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
