Sagot :

Step-by-step explanation:

[tex] {17}^{2} = {8}^{2} + {b}^{2} \\ {b}^{2} = {17}^{2} - {8}^{2} \\ {b }^{2} = 225 \\ b = \sqrt{225} = 15[/tex]

Use Pythagorean theorem

[tex]\\ \sf\longmapsto b^2=h^2-p^2[/tex]

[tex]\\ \sf\longmapsto b^2=17^2-8^2[/tex]

[tex]\\ \sf\longmapsto b^2=289-64[/tex]

[tex]\\ \sf\longmapsto b^2=225[/tex]

[tex]\\ \sf\longmapsto b=15ft[/tex]
