The formula for area of a triangle is hxb/2 so plug in the the area so the equation looks like hx5/2=10 and you get 4 for height
If she gains a card that would be a positive 1, if she sells one that would be negative 1, and if she keeps one than that would be 0.

Step-by-step explanation:
Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.
Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
In order to solve first convert both values into improper fractions:
18/5+63/10
second, convert both values to fractions with a base of ten:
36/10+63/10
finally, add the numerators:
99/10 is the final answer
