Question

Which of the following equations can be used to find the length of bc?

Answer 1

Your answer would be C.

Answer 2

For this case, by definition, we have that the Pythagorean theorem is given by:

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

Where,

c: length of the hypotenuse

a, b: lengths of the sides of the triangle

Therefore, applying the Pythagorean theorem for the triangle of the figure, we have:

`(BC) ^ 2 = 10 ^ 2 + 30 ^ 2`

Answer:

The equation for the length of BC is:

`(BC) ^ 2 = 10 ^ 2 + 30 ^ 2`

option C.

Answer 3

For this case, by definition, we have that the Pythagorean theorem is given by:

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

Where,

c: length of the hypotenuse

a, b: lengths of the sides of the triangle

Therefore, applying the Pythagorean theorem for the triangle of the figure, we have:

`(BC) ^ 2 = 10 ^ 2 + 30 ^ 2`

Answer:

The equation for the length of BC is:

`(BC) ^ 2 = 10 ^ 2 + 30 ^ 2`

option C.
