Given:
The inequality is
To find:
The solution of the given inequality.
Solution:
We have,
Isolate the variables terms on the left side.
Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.
Therefore, the correct option is D.
Answer: approximately 311 feet
I rounded to the nearest whole number since the other given values are whole numbers. The more accurate value is roughly 310.825323188148 feet.
=========================================================
Explanation:
Refer to the diagram below. When using the 47 degree as the reference angle, we know that,
We can say:
sin(angle) = opposite/hypotenuse
sin(47) = x/425
425*sin(47) = x
x = 425*sin(47)
x = 310.825323188148
x = 311
The kite is approximately 311 feet off the ground.
