Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle

sin40° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{AC}{7}$

Multiply both sides by 7, thus

AC = 7sin40° → A

Step-by-step explanation:

The sides add to 63, so:

$11+3x+11+x+2+2x+3=63 \\ \\ 6x+27=63 \\ \\ 6x=36 \\ \\ x=6 \\ \\ \implies AB=2(6)+3=15$
