We will calculate the length of the hypotenuse using the Pythagorean theorem. Suppose that the hypotenuse = c, then:

c^2 = 6^2 + 3^2

c^2 = 36 + 9

c^2 = 45

c = square root of 45

c = square root of 9 * square root of 5

c = 3 * square root of 5 ; <em>square root of 5 = approximately 2,24</em>

c = 3 * 2,24 = 6,72 = 6,7

The correct answer is 6,7.

What is the distance between (-2 1/2, -3) and (1, -3)

Igoryamba

Answer:

Step-by-step explanation:

(-2 1/2, -3) = (-5/2 , -3) & (1, -3)

$Distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(1-[\frac{-5}{2}])^{2}+(-3-[-3])^{2}}\\\\ =\sqrt{(1+\frac{5}{2})^{2}+(-3+3)^{2}}\\\\ =\sqrt{(\frac{7}{2})^{2}} \\\\=\frac{7}{2}\\\\=3\frac{1}{2}$
