What is the greatest common factor in 42& 63

The GCF of 42 and 63 is 21. This is because 21 can be divided evenly into both 42 and 63. For example, 21 × 2 = 42

and 21 × 3 = 63.

I hope this helped.

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
