should be 8/17. sin means opposite over hypotenuse. opposite=8 hypotenuse=17

you can find the hypotesnuse using Pythagoras theorem: a^2 + b^2 = c^2

8^2 + 15^2 = c^2

By Pythagoras theorem :

[tex]\qquad \sf  \dashrightarrow \: hypotenuse = \sqrt{(perpendicular) {}^{2} + (base) {}^{2} } [/tex]

[tex]\qquad \sf  \dashrightarrow \: h= \sqrt{15 {}^{2} + {8}^{2} } [/tex]

[tex]\qquad \sf  \dashrightarrow \: h = \sqrt{225 + 64} [/tex]

[tex]\qquad \sf  \dashrightarrow \: = \sqrt{289} [/tex]

[tex]\qquad \sf  \dashrightarrow \: h = 17 \: \: units[/tex]

Now, we know ~

[tex]\qquad \sf  \dashrightarrow \: \sin(A) = \dfrac{opposite \: \: side}{hypotenuse} [/tex]

[tex]\qquad \sf  \dashrightarrow \: \sin(A) = \dfrac{8}{17} [/tex]
