Answer:
To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram
Step-by-step explanation:
hope this helps :)
A. 11. mode is the one that appears the most
The angles of a parallelogram add up to 360°
and the opposite angles are equal
so you make the equation: 150+150+5x+5x=360
you solve for x
10x=60
x=6
