The volume of a cone is (1/3) that of its similar cylinder.
Thus the volume of the cone B would be:
Y = -5x + 28
will be parallel to your equation because it has the same coefficient but will also pass through (3, 13)

Hints on solving trigonometry problems:
If no diagram is given, draw one yourself.
Mark the right angles in the diagram.
Show the sizes of the other angles and the lengths of any lines that are known
Mark the angles or sides you have to calculate.
Consider whether you need to create right triangles by drawing extra lines. For example, divide an isosceles triangle into two congruent right triangles.
Decide whether you will need Pythagorean theorem, sine, cosine or tangent.
Check that your answer is reasonable. The hypotenuse is the longest side in a right triangle.
How to use the tangent ratio to find missing sides or angles?
Example:
Answer:
The last one
Step-by-step explanation:
A scalene triangle has no similarities between the angles or the sides
In the shown triangle none of the sides are similar and none of the angles are congruent therefore this is a scalene triangle
Reasons why its not the other answers
- This is not an acute triangle. In order for it to be an acute triangle all of the angles have to have a measure less than 90 degrees. There is an angle with a measure of 120 degrees the triangle is not an acute triangle
- This triangle is not an isosceles triangle. In order for it to be an isosceles triangles it has to have at least one congruent side. None of the sides are congruent therefore it is not an isosceles triangle
- This is not a right triangle. In order for it to be a right triangle one of the angles has to have a measure of 90 degrees. Because none of the angles measure 90 degrees it is not a right triangle
In conclusion the answer would be that this triangle is a scalene triangle
