The two labeled angles are alternate interior angles, and as such, they are the same.
From this result you can build the equation
and solve it for x: subtract 13x from both sides to get
and add 2 to both sides to get
Check: if we plug the value we found we have
So the angles are actually the same, as requested.
➷ The formula for circumference is
1)
Divide both sides by
d = 9.99 (consider this to be 10)
Half this to find the radius
10/2 = 5
It would be figure B.
2)
Divide both sides by :
d = 11.99 (consider this to be 12)
Divide by 2 to find the radius:
12/2 = 6
It would be figure C.
3) area =
r^2 = 48.97515909
r = 6.998 (consider this to be 7)
It would be figure D
4)
r^2 = 35.98174
r = 5.998 (consider this to be 6)
It would be figure C.
5) radius = diameter / 2
radius = 3
It would be option C
