.17 because there is a zero behind the 7! .170 and .165. .17 is bigger
First find midpoint of AB and lastly find the length of midpoint and C
The angles 1 and 2 are right angles.
As stated in the question line l is perpendicular to line m and perpendicular lines create right angles
Hope this helps :)
Think you need to add everything up
C) 12V2
12^2 + 12^2 = c^2
144 + 144 = 288
V288 = 12V2
