Answer:
I would use addition
Step-by-step explanation:
Since addition is the opposite of subtraction.
Add up the subtended arcs that these chords cut to get
44+86 = 130
Then divide that result by 2
130/2 = 65
Final Answer: choice A) 65 degrees
Answer:
-21
Step-by-step explanation:
-21 x 2 = -42 -42+16= -26
This is a true statement.
Consider two events A and B. We say they are complementary if P(A)+P(B) = 1
This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.
---------
Example:
A = the event it rains
B = the event it does not rain
P(A) = 0.30 = 30% chance of rain
P(B) = 0.70 = 70% chance it does not rain
P(A)+P(B) = 0.30+0.70 = 1
So this shows the two events are complementary.
Answer: 6
Step-by-step explanation: Because, 6 is the highest number you can multiply both with, 6x12 = 72 and 6x7 = 42
