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! :)
