Answer:

b = 34 degrees

Step-by-step explanation:

*triangles have an interior angle of 180 degrees

to find b, take the known angles (115 and 31) add them together and subtract the sum from 180:

⇒ 180 - (115 + 31)

solve:

⇒ 180 - 146 = 34

b = 34

Answer:

Step-by-step explanation:

A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34

So the answer is 34

VARVARA [1.3K]

Answer:

Step-by-step explanation:

Two events A and B are called independent, when

$P(B|A)=P(B),$

where $P(B|A)$ is the probability that B occurs given that A has already occurred.

A = randomly selected person is a student

B = randomly selected person prefer "Vikings"

B|A = randomly selected student prefer "Vikings"

Probabilities:

$P(A)=\dfrac{100}{125}=\dfrac{4}{5}=0.8\\ \\P(B|A)=\dfrac{80}{85}=\dfrac{16}{17}\approx 0.94$

Since

$0.80\neq 0.94$

we can state that events are not independent.
