Answer:

21

Step-by-step explanation:

  • AC = 64
  • AB = 7x + 8
  • BC = 3x + 6

<u>Since AC = AB + BC</u>

  • 7x + 8 + 3x + 6 = 64
  • 10x + 14 = 64
  • 10x = 50
  • x = 50/10
  • x = 5

------------------

BC = 3x + 6 = 3*5 + 6 = 21

Answer:

So we know the formula to calculate the area of the circular sector:

S=(r^2*π*a)/306°=

(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.

r - radius of the circle

a - corner of the circular sector
