The answer is 15. just replace the letters with the numbers they're equal to.
It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6

<u>Area of a Circle</u>
A circle is a geometric shape where all the points on its circumference are at the same distance to a fixed point called center. The radius is the distance from the center to any point of the circumference.
The relation of the length of the circumference to the radius is an irrational number called pi ().
Another interesting relation in a circle is the area it occupies in a 2D space. Being r the radius of the circle, the area is computed by the formula
The party hat has a radius of r= 3 inches. The area of the circular base is computed as follows
Answer:
20 senameters 2
Step-by-step explanation:
2(w+60) + 2w= 520
perimeter of a rectangle = 2(length)+2(width)
length=w+60ft
width=w
perimeter=520ft
520ft=2(w+60)+2w
