The given 2 cm is the length of the arc that the second hand had traveled for 15 seconds. Since the second hand completes a whole revolution in 60 seconds, it traveled approximately 1/4 of its circumference for 15 seconds. The length of the second hand is the radius of the circle.
2 cm = (1/4) x 2π x (L)
Solving for L gives an answer of 1.273 cm. Thus, the answer is the second choice, 1.3 cm.
It can be written as 5 x 10^ -11 or 0.5 x 10^ -10
Hope it helps.
They are called vertical angles because the definition of vertical is: <span>in a direction, or having an alignment, such that the top is directly above the bottom. The "angles opposite each other when two lines cross" match the definition.</span>
