If a pentagon is regular, then all of the sides are the same length. This means that

So, if
, the lengths of the sides evaluate to

So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.
=2 4/5
8/10+2
2+8/10=2 8/10
4/5- -2/1
(4x1)-(-2x5) divided by 5x1
=4- -10 divided by 5
=14/5
=2 4/5

Answer:
I get 17.
Step-by-step explanation:
Reduce the fraction:
3 ( 3 + 4 ) - 4
Add the numbers:
3 x 7 - 4
Multiply the numbers:
21 - 4
Subtract the numbers:
17
You would have to find the height.
To do this, you cut the triangle from the upper vertex to the base to create two new triangles.
Then you use the Law of Cosines. You could use the google calculator for this by searching “law of cosines calculator” and inputting the values, but in case of a test, the formula is a^2 = b^2 + c^2 - 2bc cosA
If you could provide an example of a triangle, I will gladly help you with the steps! Hope this helped!
