1.(07.02 MC) The lengths of three sides of a trapezoid are shown below:
Side 1: 1622 – 42 + 2
Side 2: -22 + 21 + 722
Side 3: 2 - 3z + 1822
The perimeter of the trapezoid is 1773 + 6022 + 2z - 5.
Part A: What is the total length of sides 1, 2, and 3, of the trapezoid? (4 points)
Part B: What is the length of the fourth side of the trapezoid? (3 points)
Part C: Do the answers for Part A and Part B show that the polynomials are closed under add

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
