Question

Can you answer my question please and thank you

Answer 1

Answer: 12

Explanation:

To find a length of a right triangle, we can use Pythagorean theory:

leg² + leg² = hypotenuse²

5² + b² = 13²

25 + b² = 169

b² = 144

b =
`√(144)`

b = 12

Answer 2

b = 12

Explanation:

since a² + b² = c²

we can find b by pythagorean theorem.

sqrt(13² - 5²) = b

hence,

b = 12
