Ab is obtuse acute to AD
DC is perpendicular parallel to AB
Answer:
m=3 is the slope of this equation y=3x-4
7/10 m= 0.7 m
4.1÷0.7=5.85
You would round down 5.85 to just 5, because he cannot cut less than a whole strip.
To find the exact amount of wire used in 5 strips:
5×0.7= 3.5
4.1-3.5= 0.6 m will be leftover.
