Answer 1

Answer:

AB=8.4 inches

AC=13.05 inches

Solution,

$\frac{ab}{bc} = tan \: 40 \\ ab = bc \times tan \: 40 \\ ab = 10 \times 0.84 \\ ab = 8.4 \: inches \:$

$\frac{bc}{ac} = cos \: 40 \\ \frac{bc}{cos \: 40} = ac \\ ac = \frac{10}{cos \: 40} \\ ac = 13.05 \: inches$

Hope this helps...

Good luck on your assignment..
