I hope this helps you

ACB=ABC=180-30/2=75

angle C=angle B

A+B+C=180

2B+30=180

OR

2C+30=180

B=C=75

Chad and Victoria are playing a game with a quarter and a spinner divided into sixths numbered one through six each player spins

rodikova [14]

The simple way to do this is to multiply the number of outcomes of one object times the number of outcomes in the other object. In this case a quarter has 2 sides, heads and tails. Since the spinner has 6 sections, there are 6 outcomes.

With this we can do, 2x6=12.

Therefore there are 12 outcomes
