The sum of the interior angles, s, in an n-sided polygon can be determined using the formula s=180(n-2), where n is the number o

f sides. Benita solves this equation for n and writes the equivalent equation n=s/180+2. Using this formula, how many sides does a polygon have if the sum of the interior angles is 1,260?

If you toss a coin and spin the spinner, what is the probability of landing on heads and spinning blue?
ivann1987 [24]

Answer:

Step-by-step explanation:

There are two sides on a coin, heads and tails. So, the probability  of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.
