3. darcy mounted a motion sensor so it would light a path to the door on her deck. if you know ab = 10 feet, and be and bd trisect ∠abc, what is the perimeter of the deck area to the right of the beam of light (△bdc)? part 1: what other angles or sides of △bdc can you label given that side ab is 10 feet, be and bd trisect ∠abc? label the diagram accordingly, and explain your reasoning. (4 points)

n a 30-60-90 right (special) angled triangle, the lengths are in the ratio 1:3‾√:21:3:2.

In your figure, there are three triangles of such type. Use ratios on similar triangles to calculate each length.

For example, in △BCD,BD:CD=2:1△BCD,BD:CD=2:1. Therefore BD=20BD=20

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
