Answer:
Step-by-step explanation:
Remark
The problem asks you to identify the triangles. They are similar. The reason they are similar is by AA. That means that 2 of the angles are identified as equal in each triangle.
Proof
Both triangles contain a right angle....................That's given.
The mirror has an interesting property. It is stated as the angle of incidence = the angle of reflection. That property is marked by the lines hitting the mirror towards your right. If you do not know what incidence and reflection mean, just notice that the angles are marked as equal and call it given.
The base angles are equal ....................................Given
Here it is more formally
B and D are right angles ..................... Given
<AMB = <CMD Property of a mirror
Triangle AMB similar Triangle CMD AA in 1 triangle = AA in the other.
I think the answer is 1/16 ...not for sure tho

Answer:
Width of the garden = 22.8 foot
Step-by-step explanation:
Area of the rectangular garden = 2077 square feet.
Let
Width of the garden = x
Length of the garden = 4x
Area of a rectangular garden = length × width
2077 = 4x * x
2077 = 4x²
x² = 2077/4
x² = 519.25
find the square root of both sides
x = √519.25
x = 22.787057730211
To the nearest tenth of a foot.
x = 22.8 foot
Width of the garden = 22.8 foot
It is a <span>Concave pentagon because it has an angle over 180 degrees. Otherwise it is a Convex pentagon.</span>
