Answer:

Two right angles = 180 degrees

Step-by-step explanation:

A right angle = 90 degrees

The sum of the interior angles of a triangle = 180 degrees

Two right angles (2 * 90) = 180

180 = 180

Therefore, the sum of the interior angles of  any triangle is equal to two right angles.

solve for x. if there is more than one solution, use commas to separate your answers. x/x-3 + x/2 =6x/2x-6
chubhunter [2.5K]
X/x-3 + x/2 = 6x/2x-6

⇒ x/x-3 + x/2 = 3x/x-3

⇒ x/x-3 - 3x/x-3 = -x/2

⇒ -2x/x-3 = -x/2

Two cases:
1) x = 0
2) x ≠ 0
⇒ 2/x-3 = 1/2

⇒ x-3 = 4

⇒ x = 3+4 = 7

Solutions are: x= 0,7

Hope it helps!

Which equation represents the volume of a cone with the same base and height as the cylinder below?
yawa3891 [41]

Answer:

Volume cone = one-third pi t squared k

Step-by-step explanation:

Given a cylinder with a height k and radius t, the volume of the cylinder will be πt²k.

Since a come is carved out of the cylinder with the same base and height, the volume of the cone will be a fraction of that of the cylinder since part of the cylinder will be remaining. The volume of the come will be one-third of the volume of a cylinder. This is expressed as shown:

Volume of the cone = 1/3 of πt²k

Volume of the cone = 1/3πt²k
