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:
- Grayson had 10 inches of snow in his lawn
- the snow falls at a constant rate of 0.5 inches per hour
- no snow was melting
- the snow has fallen for 3 hours
Let y be the height of the snow in the lawn
Grayson had 10 inches at the beginning (at t=0) so y= 10
3 hours passed so y= 10 + 3*0.5 = 11.5 inches
Grayson had 11.5 inches after three hours
Assuming that the snow continued to fall for an unkhown time t
y = 0.5*t + 10
we had 10 at the beginning so we add 10 (+10)
the snow is growing by 0.5 inches in the single hour so we multiply by 0.5
t is the time and it can 4, 5, 6 ...... hours
Just like a function :
- 0.5 is the slope
- t is the variable
- 10 is the y-intercept
Answer:
18
Step-by-step explanation:
Factors of 54
1, 2, 3, 6, 9, 18, 27
Factors of 72
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36
Factors of 18
1, 2, 3, 6, 9, 18.
Greatest Common Factor
We found the factors and prime factorization of 72, 54 and 18. The biggest common factor number is the GCF number.
So the greatest common factor 72, 54 and 18 is 18.
Step-by-step explanation:
The answer is -51, hope this helps
