Match each multiplication expression on the left with the best estimate of its product on the right. 32.9 x 4.81
(60)(4) = 240
29.3 5.9
(30)(5) = 150
59.3 x 3.57
(50)(30) = 1,500
46.7 x 31.7
(30)(6) = 180
81.4 x 32.1
(80)(30) = 2,400

32.9 x 4.81 = (30)(5)=150

29.3 x 5.9 = (20)(6)=180

59.3 x 3.57 = (60)(4)=240

46.7 x 31.7 = (50)(30)=1,500

81.4 x 32.1 = (80)(30)=2,400

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
