The laws of sines is already indicated in the provided images.
1. sin20/3.3 = sinC/5.4
Thus, angle C is 34.03 degrees. To find angle B: 180 - 20 - 34.03 = 126 degrees. Using the law of sines,
sin20/3.3 = sin(126)/b
b = 7.8 units
From this answer, we can already tell that the answer is letter C: <span>3 units and 7.8 units.
2. Angle J = 180 - 120 - 40 = 20 degrees. Then,
sin(20)/2 = sin(120)/k
k = 5.1 units</span>
Answer:
A
Step-by-step explanation:
This can be easily understood using the triangle inequality theorem:
"In a triangle, the combined lengths of any two sides must always be greater than the length of the third side."
- Is 10+5 greater than 4? YES
- Is 10+5 greater than 5? YES
- Is 5+4 greater than 10? No!
Since all of them doesn't hold true, we cannot make any triangle. The answer is A, 0.
