19/20 is less then 8/9. And I know how this fractions are labeled down in blocks
Answer:
41
Step-by-step explanation:
BDA = DBC+CBA
84=5x+3 + 6x-7
Combine like terms
84 = 11x-4
Add 4 to each side
84+4= 11x -4+4
88 =11x
Divide each side by 11
88/11 = 11x/11
8 = x
We want angle ABC
ABC = 6x-7
=6*8 -7
=48-7
=41
1) Find the area of the circle: Ac = pi*(2 ft)^2 = 4pi ft^2
2) Multiply this result by 3/4: (3/4)(pi)(4ft^2) = 3 pi ft^2
3) Find the area of the square: As = (2 ft)^2 = 4 ft^2
4) Add together the results of steps (2) and (3): 3 pi + 4 ft^2 (answer)
