ANSWER:
d. x = 15, y= 15√3
EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have
We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15
We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.
x = 15
y = 15√3
Sorry if I explained it too thoroughly but I’ll be glad to answer any questions or clarifications
Letter D is the answer. Good luck!
Answer: $12,723.45
Step-by-step explanation:
Details of each play area :
The radius of circle = 18 feet long
Cost of fake grass per square foot = $12.50
Therefore,
We can obtain the Area of the play area by calculating the area of the circle:
Area of a circle = πr^2
Area = π × 18^2
Area = 1,017.876ft^2
Since the cost per square foot is $12.50
Therefore, Cost of 1,017.876 ft^2 equals
Cost per square foot × Area of play area
($12.50 × 1,017.876)
= $12,723.45
