Question

Pls help me on this !!!

Answer 1

9

Explanation:

To solve this question you need the formula of hypothenuse theorem, I personally use
`a^(2) + b^(2) = c^(2)`.

Since
`c^(2)` is the hypothenuse, and the hypothenuse in this case is 15, the equation will be
`12^(2)+ b^(2) = 15^(2)`.

144+
`b^(2)`=225

subtract 144 from both sides

`b^(2)`= 81

`\sqrt{b^{} } = √(81)`

b=9
