Question

stil means ultra sound​

Answer 1

..In triangle ABC,

BD is the height

Therefore by pythagoras theorem,

\begin{gathered}ac^{2} = bc^{2} + ab^{2} \\ ac ^{2} = 12 ^{2} + 5 {}^{2} \\ ac^{2} = 144 + 25 = 169 \\ ac = 13 \end{gathered}

ac

2

=bc

2

+ab

2

ac

2

=12

2

+5

2

ac

2

=144+25=169

ac=13

SINalpha=opposites side / hypotenuse

=BC /AC

=5/13
