In a right triangle, the cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. Figure 20.7 A right triangle with tangent ratio 9/14. sin ∠A = 9√277/277 and cos ∠A = 14√277/277.
Answer: Skip counting by 12
The python is 2.6pi meters long. This is the circumference because it's the distance around the circle. So, C = 2.6pi
We will plug this into the formula below and isolate r
C = 2*pi*r
2.6pi = 2*pi*r
2.6 = 2*r .... divide both sides by pi
2.6/2 = 2r/2
1.3 = r
r = 1.3
Since r = 1.3, this means that the radius is 1.3 meters.
