For this figure, find the value of x.

x = [1]

do i add all three angles together then take 180 and subtract what i got from the angles and thats my answer? which by the way is 79+23+50+x=180 then 180 - ? =x

Step-by-step explanation:

The total number of people mentioned in this problem is 15. 15 will be the denominator for the probability in fraction form. The sum of the # of people that include lifeguards and managers will be the numerator.

Therefore, the probability that the person picked is either a manager or a lifeguard is 10/15 [because there are 2 managers and 8 lifeguards; 2 + 8 =10].

Fraction form of probability: 10/15

Decimal form: 0.6 repeated

Percent form: about 66.67%
