Answer:

  • AB = 7 cm

Step-by-step explanation:

<u>Use the law of cosines to find the side AB:</u>

  • AB = \sqrt{(x + 3)^2+x^2-2x(x+3)cos (60)} =
  • \sqrt{x^2+6x+9+x^2-x^2-3x}  = \sqrt{x^2+3x+9}

<u>Use the Heron's area formula next:</u>

  • A = \sqrt{s(s - a)(s-b)(s-c)}, where s- semi perimeter
  • s = 1/2[x + x + 3 + \sqrt{x^2+3x+9}) = 1/2 (2x + 3 + \sqrt{x^2+3x+9})
  • s - a = 1/2 (2x + 3 + \sqrt{x^2+3x+9} - 2x - 6) = 1/2 (\sqrt{x^2+3x+9 } - 3)
  • s - b = 1/2 (2x + 3 + \sqrt{x^2+3x+9} - 2x) = 1/2 (\sqrt{x^2+3x+9} + 3)
  • s - c = 1/2 (2x + 3 + \sqrt{x^2+3x+9} - 2\sqrt{x^2+3x+9}) = 1/2 (2x + 3 - \sqrt{x^2+3x+9})

<u>Now</u>

  • (s - a)(s - b) = 1/4 [(x²+3x+9) - 9] = 1/4 (x² + 3x)
  • s(s - c) = 1/4 [(2x + 3)² - (x² + 3x + 9)] = 1/4 (3x²+ 9x) = 3/4(x² + 3x)

<u>Next</u>

  • A² = 3/16(x² + 3x)(x² + 3x)
  • 300 = 3/16(x² + 3x)²
  • 1600 = (x² + 3x)²
  • x² + 3x = 40

<u>Substitute this into the first equation:</u>

  • AB = \sqrt{40 + 9} = 7 cm

Beatriz is reading a book tgat has 530 pages. If she reads 10 pages a day, how many days will it take her to finish the book?
Art [367]
The equation you want to use is this:

10x = 530                             10 pages for x days

x = 530/10                            
530 pages divided by 10 pages

So the answer is,

53 days
