Answer:

b = 9.2

Step-by-step explanation:

We can use the law of sines

sin A sin B sin C

-------------- = ------------= ----------------

a b c

We only need the first two parts

AC = b

Sin 31 sin 108

--------- = ----------------

5 b

Using cross products

b sin 31 = 5 sin 108

Divide each side by sin 31

b = 5 sin 108 / sin 31

b = 9.232875807

To the nearest tenth

b = 9.2

y = mx + c ( m is the slope and c the y- intercept )

Here m = 7 and c = - 5, then

y = 7x - 5 ← equation of line
