The two base angles of an isoceles triangle are equal so we can conclude that

2x - 20 = x + 8

Now we just need to solve for x:

2x - 20 + 20 = x + 8 + 20

2x = x + 28

2x - x = x + 28 - x

x = 28

So, angle B = x + 8 which is 28 + 8 = 36°

A cylinder has a volume of 390 cm³. If a cone has the same dimensions as the cylinder then what is the volume of the cone.

dangina [55]

Answer: The volume of the cone is 130 cubic centimeters.

Step-by-step explanation:

We know that to find the volume of a cylinder you will use the formula

V= $\pi$ $r^{2} *h$ Where r is the radius and h is the height.

And to find the volume of a cone you will use the formula

V= $\pi$ $r^{2}$ *h /3

So if they have the same dimensions which is the height and the radius then we will just divide the volume of the cylinder by 3 to find the volume of the cone.

V = 390/3

V = 130 cm^3
