and 
Step-by-step explanation:
Given:
≅
From the given Data, we can conclude the following:
1. Since two sides of the triangle ABC are congruent, therefore its an isosceles triangle.
2. 
°. This shows that the line BE is perpendicular to AC. By property of isosceles triangle, the line which passes from the vertex of the largest angle of triangle and cuts the opposite side(base) perpendicularly is the perpendicular bisector of the side and angle bisector of the angle.
∴ 
[ Definition of Angle bisector]
∴

Answer:
460 ft^2 of carpet will be replaced
Step-by-step explanation:
You need to find the area of the room and then take away the area of the six bookcases
<u>Area of the room</u>
20*20=400ft^2
35-20=15ft
(15*20)/2=150ft^2
400+150=550ft^2 total room area
<u>Area of bookcases</u>
2.5*6*6=90ft^2 total bookcase area
<u>room area - bookcase area = carpet area</u>
550-90=460ft^2
The answer is $7.14!
All you have to do is subtract 10 by 2.86.
