Answer:
∠F = 50°
Step-by-step explanation:
The sum of all three angles in a triangle = 180°
∠F = 180° - 30° - 100° = 50°
Answer: There are infinitely many solutions.
Step-by-step explanation:
Given, Two lines, A and B, are represented by the following equations:
Line A: 3x + 3y = 12
Line B: x + y = 4
By comparing to the equations and respectively , we have
Now ,
i.e.
It implies the gives lines are co-incident (linearly dependent).
That means it has infinitely many solutions.
So, the correct answer is "There are infinitely many solutions.".
