Answer: b is 35
step by step explanation
It should be B. right angle and C. complementary angles
Since the beacons rotate together, the angular speed is constant.
From the time you see the first beacon, you have to wait for the lighthouse to make 120°, i.e. 1/3 of a whole turn.
So, if T is the time it takes for the lighthouse to make a whole turn, the interval between the first and the second beacon is T/3.
The interval between the second and third beacon is the amount of time it takes to the lighthouse to make the remaining 2/3 of a turn, so that you'll see the first beacon again. So, this time is 2T/3
So, the ratio is

So, the time between the second and third beacon is twice as much the time between the first two.
Braves : 5 + 4 + 0 = 9
Giants : 6 + 1 + 3 = 10
Giants scored 1 more run then the Braves in the series.
Put your number into the half-angle formula and simplify.

The appropriate selection is ...
