Step-by-step explanation:
Srry about the messy sketches
hope you got the general idea
if not :
Each figure got it's own sum of its angles. All I did was to sum all the given angles and made it equal to that number(360/540/720).
As a result, I found the value of the variable and after that the angles themselves.
Answer:
x=19
Step-by-step explanation:
(3x-3)° = [6(x-10)]°
3x-3= 6x-60
-3=3x-60
57=3x
÷3
x=19
In terms of diameter (d), the area (A) of a circle is given by the formula
A = (π/4)d²
You have d=20 yd, so the area of the circle is
A = (π/4)×(20 yd)² . . . . substitute the given information into the formula
A = 100π yd² . . . . . . . . do the arithmetic
A ≈ 314.16 yd²
