Answer:
Use this equation to find out!
Step-by-step explanation:
Since you didn't specify the n-gon, you have to use this equation to find out!
Number of Diagonals = n(n-3)/2
Hope this helps! :)
An isosceles triangle is one where two sides are equal to each other. The third side is of a different length.
At first glance, choice A looks like the answer because we have two sides that are the same length (the sides of length 1). However, this triangle is not possible because 1+1 = 2 which is less then 3. For a triangle to be possible, adding up two sides must be larger than the third side. I'm using the triangle inequality theorem here.
This works for choice D since 6+6 = 12 which is greater than 5. Also 5+6 = 11 which is greater than 6. So the answer is choice D

Let's apply trivial identities here. We know that cos(-π / 4) = √2 / 2, sin(-π / 4) = - √2 / 2, cos(-π / 2) = 0, sin(-π / 2) = - 1. Let's substitute those values,
