HELP ME PLS explain why

Anika [276]

Answer: 110 square cm

=======================================================

Explanation:

All sides of a regular polygon are the same length. So the bottom side is also 8 cm.

Draw lines from the center to each vertex of the pentagon. Five triangles form. Each triangle has a base of 8 and a height of 5.5 (since all five triangles are congruent)

area of one triangle = 0.5*base*height = 0.5*8*5.5 = 22

area of five triangles = 5*(area of one triangle) = 5*22 = 110

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Identify

Point (6, 8)

Point (6, 6)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{6-8}{6-6}$
[Fraction] Subtract: $\displaystyle m = \frac{-2}{0}$
Simplify: m = undefined

∴ We have a vertical line at x = 6.
