x = 200 + (n - 1)5.

<em>[x = The distance Freya sprints on day 21]</em>

The altitude to the hypotenuse of a right triangle divides the hypotenuse into segments 3cm and 27cm long. Find the length of th

marissa [1.9K]

To find the length of the altitude, we have to use the ratios of the similar sides.
Let the length of altitude=x
Ratio of sides:
$\frac{x}{3} = \frac{27}{x} \\
Cross \ multiply \\
 x^{2} =81 \\
Take \ square \ root.\\
 \sqrt{x^2}= \sqrt{81} \\
x=9 \\$
So length of altitude is 9 cm.

Answer: 9 cm
