An 8 by 19 ft wall has three 4 by 5ft windows. The area of three windows is what percent of the area of the entire wall

1 answer:

6 0

Area of the wall = 8 x 19 = 152 ft square
Area of the window = 4 x 5 = 20 ft square
Area of 3 windows = 20 x 3 = 60 ft square
The percent area of 3 windows from area of the wall = 60/152 or approximately .395 or 39.5%

The circle is inscribed in Triangle AEC. Which are congruent line segments

Harlamova29_29 [7]

Answer:

E-F and E-D

C-B and C-D

Step-by-step explanation:

The circle and triangle are as shown. The options are:

A-B and C-B
E-F and E-D
E-D and C-D
A-F and E-F
C-B and C-D

By drawing radius lines from the center of the circle to the tangent points B, D, and F, we can divide the triangle into 3 kites. Therefore, only segments that are legs of the same kite are congruent. So the answer must be E-F and E-D, and C-B and C-D.
