Question

I need help with this​

Answer 1

Use Pythagorean theorem

`\\ \sf\longmapsto b^2=h^2-p^2`

`\\ \sf\longmapsto b^2=17^2-8^2`

`\\ \sf\longmapsto b^2=289-64`

`\\ \sf\longmapsto b^2=225`

`\\ \sf\longmapsto b=15ft`

Answer 2

Explanation:

`{17}^(2) = {8}^(2) + {b}^(2) \\ {b}^(2) = {17}^(2) - {8}^(2) \\ {b }^(2) = 225 \\ b = √(225) = 15`
