Answer:
Step-by-step explanation:
Turn the question around so it is easier to see.The open end is closest to n.
6n>48 Divide by 6
6n/6>48/6
n > 8
So all you have to do is choose 3 values greater than 8
How about 9,10,11
M<ABC= (AD+CE)/2=(100+45)/2=145/2
m<ABC=72° 30'
A is the correct answer to this problem
