Answer:
They're the same angle. I would look up transversals so you could understand it a bit more. I'll upload a picture of a transversal in my answer but you should search it anyways.
Anyways,
To solve, you set 160 equal to the other side.
160 = 3x + 10
150 = 3x
x = 50
Answer:
Step-by-step explanation:
Circumference Formula: 2pi x r
Radius = 20.5
Plug it in:
2(3.14) x 20.5
6.28 x 20.5 = 128.74
Then, convert to pi terms.
128.74 = 41 pi
Therefore the circumference of a circle with a radius of 20.5m is 41pi.
If the bottom number is the same thing as 1 then it will be 1, if not, then it will be a mixed fraction
