A right triangle has a segment from the right angle that meets the hypotenuse at a right angle at point \( p \). Point \( p \) splits the hypotenuse into two segments whose lengths are 16 units and 4 units. Find the distance from the perpendicular line to the right angle. (1 point)

The midpoint between two points is \( \{1,5\rangle \). One of those points is \( \{8,3\rangle \), find the other.

\( (-9,-1) \) and \( (12,14) \) Slope \( = \)

7. A village with an actual area of \( 1 \mathrm{~km}^{2} \) is represented by an area of \( 4 \mathrm{~cm}^{2} \) on a map. (a) Express the scale of this map in the form \( 1: n \), where \( n \) is an integer.

5. Em um polígono, a razão entre a soma das medidas dos ângulos internos e a soma das medidas dos ângulos externos é igual a \( \frac{7}{2} \). Quantos lados tem esse polígono?

Draw a graph of the line that contains the given point and has the given slope. \( (-5,0) ; m=\frac{1}{5} \)
