- It's very long so I'm not giving answers but here's how i would do it:
- use Pythagoras
where c is the longest side - use sine rule
where lower cases are the sides, and capitals are their opposite angles.
e.g for 15:
a = 3, b is missing, c = 10
A is missing, B is ?, C is 90
Answer:
What does this even say maybe I can try and help.
Answers are B, C, and D
If Q = 33, then the two slopes are both 33. As long as the y intercepts are different, then the two lines will be parallel leading to no intersections. No intersections means no solutions.
Note: Choice A leads to infinitely many solutions as we'll have identical copies of the same expression on each side (33x+25 = 33x+25). This is why we can rule choice A out.
