Question

What is the length of BC

Answer 1

`BC \approx 2.24`

Explanation:

We can form a right triangle with BC as the hypotenuse.

Then, we can apply the Pythagorean Theorem to solve for the length of BC.

The dimensions of this right triangle are base: 2, height: 1.

Plugging these values into the theorem:

`a^2 + b^2 = c^2`

`2^2 + 1^2 = BC^2`

`4 + 1 = BC^2`

`5 = BC^2`

`\boxed{\sqrt5 = BC}`

We can approximate
`\sqrt5` as:

`\boxed{BC \approx 2.24}`
