How many ways can the number 10 be written as the sum of exactly three positives and not necessarily different integers if the order in which the sum is written does not matter? For instance,
10 = 1 + 4 + 5 is one such sum. This sum is the same as 10 = 4 + 1 + 5.

Step-by-step explanation:

1+2+3+4=10

3+3+3+1=10

do the others yourself

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
