Answer:
A) Not mutually exclusive
Step-by-step explanation:
Given
Required
Determine if they are mutually exclusive or not
Mutually exclusive are defined by:
So, we have:
Take LCM
By comparing:
---- Calculated
---- Given
We can conclude that A and B are not mutually exclusive because:
24/.30 is how you would get your answer and 80
36. If 7/11 did bring one, then 4/11 didn't. 4*9=36
Answer:
2 degrees and 178 degrees.
Step-by-step explanation:
So, remember if 2 angles are supplementary, they equal 180 degrees. Let's call the smaller angle x, meaning the bigger angle, which is 89 times the size of the smaller angle, would be 89x. Now let's put that into an equation.
180 = x + 89x
We now have to group the x's together:
180 = 90x
Now in order to determine x, we have to divide by 90 on both sides.
X= 2
So we know that the smaller angle is 2, meaning that if the larger angle is 89 times the size, the larger angle would be 178.
