Answer:
x=12
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
5x+8x+2x =180
Combine like terms
15x = 180
Divide by 15 on each side
15x/15 =180/15
x=12
Answer:
Your answer is C, 10.7cm
Step-by-step explanation:
The two flat sides of the figure are 3 cm, so that part of the perimeter = 6cm
3cm is the radius of what would be a whole circle. We'll calculate the circumference, then divide by 4.
Circumference = (2)(pi)(r)
C = (2)(3.14)(3)
C = 18.84
18.84/4 = 4.71
Add 4.71 to the 6 cm above, = 10.71
Let me know if you have questions about this.
Answer:
706.5 sq ft
Step-by-step explanation:
If the farthest point is 30 feet away, the diameter of the circle is 30, so the radius is 15.
Area of a circle is pi r*2
3.14 x 15^2 = 706.5 sq ft
