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.

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
