Question

what is the formula diagonal of a parallelogram ​

Answer 1

In a parallelogram, the diagonals bisect each other, so you can set the labeled segments equal to one another and then solve for . \displaystyle 20 - 3x = 2x - 4 \rightarrow 24 = 5x \rightarrow 4.8 = x. Then, substitute 4.8 for in each labeled segment to get a total of 11.2 for the diagonal length.

Answer 2

Answer:

real-life examples of diagonals are, and how to use the formula, # of Diagonals = n(n − 3)2 # o f D i a g o n a l s = n ( n - 3 ) 2 , where n is the number of sides (or vertices) of the polygon.

Explanation: In a parallelogram, the diagonals bisect each other, so you can set the labeled segments equal to one another and then solve for . \displaystyle 20 - 3x = 2x - 4 \rightarrow 24 = 5x \rightarrow 4.8 = x. Then, substitute 4.8 for in each labeled segment to get a total of 11.2 for the diagonal length.
