Answer:
<em>Option D is correct</em>
Step-by-step explanation:
Applying the cosine theorem for triangle ABC, you would have:
cos (angle BAC) = (BA^2 + CA^2 - BC^2)/(2*BA*CA)
= (10^2 + 18^2 - 20^2)/(2*10*18)
= 24/360
=> angle BAC = ~86 deg
Hope this helps!
There is no mode because the mode represents the most frequently occurring value in a data set. A data set may have more than one mode. It is one of the measures of central tendency.
Answer:
D
Step-by-step explanation:
Z is the only relation that does not pass the vertical line test, so Z is not a function.
Answer: D
To know the answer to that, you kneed to know a value of x or y to solve for them
