Answer:

a = 36

Step-by-step explanation:

We use pythagoras theorem here.

h = 60

p = 48

b = a

h² = p² + b²

60² = 48² + b²

3600 = 2304 + b²

b² = 3600 - 2304

b² = 1296

b = 36

Which is the best estimate for the diagonal of a rectangle with a width of x and a length of 2x, if x is 1.33?
german

The best estimate for the diagonal of the rectangle is 3 ⇒ B

Step-by-step explanation:

In a rectangle:

  • The length and the width are perpendicular
  • The length of its diagonal = \sqrt{(length)^{2}+(width)^{2}} (the diagonal is the hypotenuse of a right triangle whose legs are the length and the width of the rectangle)

∵ The width of a rectangle = x

∵ The length of the rectangle = 2x

∵ The diagonal = \sqrt{(length)^{2}+(width)^{2}}

- Substitute the length by 2x and the width by x

∴ The diagonal = \sqrt{(2x)^{2}+(x)^{2}}

∴ The diagonal = \sqrt{4x^{2}+x^{2}}

∴ The diagonal = \sqrt{5x^{2}}

∵ x = 1.33

- Substitute the value of x by 1.33 to find the diagonal

∴ The diagonal = \sqrt{5(1.33)^{2}}

∴ The diagonal = 2.973

∴ The diagonal ≅ 3

The best estimate for the diagonal of the rectangle is 3
