Answer:brainly?
Step-by-step explanation:
If the angles of one triangle are equal to the angles of another triangle, then the triangles are said to be equiangular.
Equiangular triangles have the same shape but may have different sizes. So, equiangular triangles are also called similar triangles.
For example, triangle DEF is similar to triangle ABC as their three angles are equal.
The length of each side in triangle DEF is multiplied by the same number, 3, to give the sides of triangle ABC.
They is 9dime and 13 Nickels because 13 x5=65 and 9 x10=90 .So 0.65+ 0.90= 1.55.
Answer:
I got that AE^2 = 8EC^2
Step-by-step explanation:
Here's what I did. I probably did this wrong, but this might give you an idea on how to solve it.
First, create equations:
AB = BC = AC = DE = 2EC
BD= BC = EC
Then, I used pythagorean theorem (since AD is perpendicular to BC): AD^2 + DE^2 = AE^2
Substitute: (2EC)^2 + (2EC)^2 = AE^2
Simplify: 4EC^2 + 4EC^2 = AE^2
AE^2 = 8CE^2
