Answer:

Step-by-step explanation:
If the two events are disjoint, then P(A or B)=P(A)+P(B).
We were given that:

and

This implies that:

We simplify the right hand side to obtain:

The total is 219 miles.
He rides at 38 mph and walks at 4 mph for 8 hours. If he rides for h hours, he walks for 8-h hours.
Set them equal to each other:
219=38h+4(8-h)
Solve and you should get 5.5 hours on the bicycle and 2.5 hours walking.
Since it's angle side angle, just use law of sine,
a/sin(A)=c/sin(C)
find C first by subtracting 16 and 72 from 180
C=92
get c is about 58
