Let x, y and z three real numbers. write an algebraic expression to denote the product of z, x and y

The product of x, y and z would be x*y*z or we can simply write xyz without the asterisks. A product is the result of multiplying two or more numbers.

The order of multiplication does not matter. Example: 2*5 = 10 and 5*2 = 10

i do not know the answer

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
