Answer:
(-2y+5x) / (3x - 2y)
Step-by-step explanation:
If we write this sentence, we have:
((-2/x) + (5/y)) / ((3/y) - (2/x))
If we do LCM in the denominators of each fraction, we have:
((-2y+5x)/xy) / ((3x - 2y)/xy)
We can cut the 'xy' in the numerator and denominator of the whole fraction:
(-2y+5x) / (3x - 2y)
The final expression we have is (-2y+5x) / (3x - 2y)
Answer:
Step-by-step explanation:
The angle 
is located in Quadrant II.
From trigonometry, we know that:
Now, in Quadrant II,
- The x-axis is negative
- The y-axis is positive
Therefore, the Adjacent angle to 
Therefore:
Answer:84
Step-by-step explanation:Using proportions, it is found that the height of the lighthouse is of 84 ft.
This question is solved by proportions, using a rule of three.
For a height of 5.25 feet, the shadow is of 8 feet. What is the height when the shadow is of 128 feet?
The rule of three is:
5.25 feet - 8 feet
x feet - 128 feet
Applying cross multiplication:
The height of the lighthouse is of 84 ft.
