Where are the quadratic equations?
This is the graph that I drew to figure out the answer to this question.
We have been given that in triangle ABC angle A=45 angle B =40 and a=7. We are asked to find the equation that we can use to solve for 'f'.
We have two angles and opposite sides to these angles.
We will use Law of Sines to solve our given problem.
, where a, b and c are opposite sides corresponding to angles A, B, and C respectively.
The angle opposite to side b is 40 degrees and angle opposite to side a is 45 degrees.
Upon substituting these values in Law of Sines, we will get:

Therefore, our required equation would be
.
Answer:
6x - 8
Step-by-step explanation:
2(3x – 4)
Distribute
2*3x - 2*4
6x - 8
The answer would be B and D. This can be found by putting the x and y values into the inequality to find whether or not they are true.
