Answer:

? = 4.29

Step-by-step explanation:

Remark

Let x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.

Equation

14/(14+ 4) = 15/(x + 15) Combine like terms on the left

14/18 = 15/(x + 15) Cross multiply

14*(x + 15) = 18 * 15 Simplify the right

14(x + 15) = 270 Divide by 14

x + 15 = 270 / 14

x + 15 = 19.29 Subtract 15 from both sides

x = 19.29 - 15

x = 4.29

$AB = \sqrt{ ({3 - ( - 2)})^{2} + ({4 - 0})^{2} } \\$

$AB = \sqrt{ ({3 + 2})^{2} + {4}^{2} }$

$AB = \sqrt{ {5}^{2} + {4}^{2} }$

$AB = \sqrt{25 + 16}$

$AB = \sqrt{41}$

$AB = 6.403$

$AB = 6.4$
