If you look at either diagonal (line joining opposite angles) it forms 2 triangles that are identical, both in size and shape, but that are in different positions. So by finding the area of one using <u>base x height ÷ 2,</u> and then adding them together, you get the area of the polygon.
However, you will find that that would be the same as just doing <u>base x height</u>, so the area of a parallelogram is just that.
X + x + 1 = -249
2x = -250
x = -125
-125 + 1 = -124
The numbers are -125 and -124
Answer: x = 8/5
Explanation:
5x-2 = 6
5x = 6 + 2
5x = 8
x = 8/5
