Answer:
5
Step-by-step explanation:
1200cm3 = 12cm * 20cm * Xcm
1200/12 = 100 = 20*X
100/20 = 5 = X
18.46
find the area using SSS, then solve for height
Just solve.
<em>The endpoint coordinates for the mid-segment are: and </em>
According to the given diagram, the coordinates of the vertices of are: and
Now, the endpoints of the mid-segment of which is parallel to will be the mid-points of sides and .
<u>Formula for the coordinate of mid-point</u> : , where and are two endpoints.
So, the mid-point of will be:
and the mid-point of will be:
Thus, the endpoint coordinates for the mid-segment of that is parallel to are and
if his height is H, and she is 7 inches shorter than him, her height can be represented by the algebraic equation H-7
