Answer:
a
Step-by-step explanation:
area of parallelogram is equal to base times height 7 * 4
Let's call them: W and L
Then area: A = W × L
We can replace: L = 2 × W
So: A = W × 2W=98→
2W^2=98 →W^2=98/2=49
→W=√49=7
→L=2×W=2×7=14
Conclusion: The rectangle is 7*14 ft
Hope this helps :)

Answer:
Option (1)
Step-by-step explanation:
<em>For convenience sake, I will be omitting the arguments of the trig functions.</em>
3sin = sin - sqrt(3)
2sin = -sqrt(3)
sin = -sqrt(3)/2
So, the answer is 4pi/3 and 5pi/3.
