How do we solve frac{n}{4} =3

n=12

Step-by-step explanation:

-This questions tests our ability to group together like terms by removing the denominator.

- Given the equation , we solve for n by removing the denominator as by multiply both sides of the equal sign by it:

Hence, n=12

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
