Answer: the second answer
Step-by-step explanation:
If we want to find an inequality with no solution, that means we can expect no x and an unbalanced inequality (e.g., 3<0 which is untrue).
The second one is like that because the inequality is
3+4x2(1+2x)
If we solve it out, we get
3+4x2+4x
When you remove the variable from both sides, you now have
32
This statement is false, since 2 will never be greater than 3.
If we look at the others, we can see that there are answers for all of them.

Step-by-step explanation:
Sine theorem: in any triangle, the ratio between a side and the sine of the opposite angle is constant
In our case, for the left triangle,
Time to grab a calculator and crunch numbers. Double check your calculator is in degrees and not in radians (plug in sin 30°, if you're getting 0.5 you're good) and you will get
Same difference with the right triangle. With the same calculations
