Difference between the number of marbles Leah has than Dan has = 28

According to question,

of Leah's marble = of Dan's marble

So, using the ratio, we have

Number of marbles Leah has = 12x

Number of marbles Dan has = 5x

So, our equation becomes,

So, Number of marbles Leah has

Hence, there are 48 marbles that Leah has.

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
