Answer:
1)
2)
Step-by-step explanation:
1)
The two triangles are similar by AA similarity.
That means .
We can add to both sides to get .
We can then subtract from both sides to get .
We know that the because they both lie on a straight line.
We can plug in for to get .
We can divide both sides of the equation by to get .
We then add to both sides to get .
So, and we're done!
2)
Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to , we have that .
We can subtract a and an from both sides to get .
We then divide both sides of the equation by to get .
We do the same thing for . On the other side of the trapezoid, we have that .
We combine like terms on the left side to get .
We subtract a from both sides to get .
We divide both sides of the equation to get .
So, and we're done!
Answer:
5
Step-by-step explanation:
The mean is the average so add up all values of the data points and divide by the amount of data points.
<em>1.6/3 = 16/30 = 8/15 </em>
<em> Volume Ratio: 512:27
