A certain television is advertised as a 13-inch TV (the diagonal length). If the width of the TV is 12 inches, how many inches tall is the TV?

The TV is 5 inches tall

Step-by-step explanation:

Let us revise the Pythagoras Theorem

In any right triangle

The tall and the width of the TV and its diagonal formed a right triangle whose legs are the tall and the width of the TV and the hypotenuse is the diagonal of the TV

∵ Width of TV = 12 inches

∵ Diagonal of TV = 13 inches

- By using Pythagoras Theorem

∵ (Diagonal)² = (width)² + (tall)²

∴ (13)² = (12)² + (tall)²

∴ 169 = 144 + (tall)²

- Subtract 144 from both sides

∴ 25 = (tall)²

- Take √  for both sides

∴ 5 = tall

∴ The TV is 5 inches tall

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
