Answer:
a = √58
Step-by-step explanation:
a² + b² = c²
Fill in the values we know:
a² + 5² = √83²
a² + 25 = 83
Subtract 25 from both sides:
a² + 25 - 25 = 83 - 25
a² = 58
Square root both sides to get 'a' by itself:
√a² = √58
a = √58
Answer: 14 units.
Step-by-step explanation:
You can find arc length using the radius by this formula:
θ =
, where s = the length of the arc and r = the radius.
So, your equation is
2 = s/7
Therefore, your arc length is 14 units.
If
, all angles would be equal, resulting in similar triangles. So B is right
