Answer:
The correct option is C ) 109.5°
Therefore,
Step-by-step explanation:
Given:
In Triangle DEF
d = 10
e = 18
f = 12
To Find
angle E = ?
Solution:
In Triangle DEF , Cosine Rule says
Substituting the values we get
Therefore,
............As it is in Second Quadrant
Therefore,
Option A:
The probability that Everett and Finley end up with an even number and a blue disk is .
Solution:
Given data:
Everett is rolling a block with numbers = {1, 2, 3, 4, 5, 6}
Finley is drawing one disk from basket with colors = {blue, red, yellow}
Total number of numbers = 6
Total number of colors = 3
Divide numerator and denominator by the common factor 3.
Option A is the correct answer.
Hence the probability that Everett and Finley end up with an even number and a blue disk is .
