Answer:
b=204
Step-by-step explanation:
The law of sine states that: 
We know that a triangle has 180° total, so we can subtract the two angle measures we know to find the third angle:
°.
Using these two things, we can come up with the equality
, which we can use to solve for side b.
, so we know that
.
Next, we would multiply both sides by b to get
.
Sin49°≈0.75471, so to find b we would multiply 0.75471×270=203.77
Since the problem asks us to round to the nearest whole number, b=204
Hope this helps! :)

Answer:
<h2>24 miles</h2>
Step-by-step explanation:
If each lap is 1/8 of a mile, then we have to do 3x8 to get our answer.
8x3=24
So hence, Rex has to go 24 times around his block to ride his bike for 3 miles.
Thanks!
