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

Answer:
I believe it is the last one i'm not sure
Step-by-step explanation:
So l=8 and 8+2.5=10.5
which means the length of the second rectangle is 10.5
w=6.2 and 6.2-1.4=4.8
which means the width of the second rectangle is 4.8
The formula for area of a rectangle is length×width
10.5×4.8=50.4 so the area of the second rectangle is 50.4 squared
