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
.

It rises 11 degrees
Step by step explanation
Answer:
1.Factor both the numerator and the denominator.
2.Write as one fraction.
3: Simplify the rational expression.
4: Multiply any remaining factors in the numerator and/or denominator.
Step-by-step explanation:
We have that (x) + (x+2) + (x+4) = 126 so 3x + 6 = 126 can be used to find the first integer.
3x + 6 = 126
3x = 120
x = 40
The numbers are 40, 42, 44
