A)He can cut 5 strips of of 7/10m.
7/10=0.7m
0.7*5=3.5m
3.5m of wire wil be used in cutting possible 7/10m pieces.
b)Leftover will be 0.6m.
4.1-3.5=0.6m





Just remember that in the form of
, you get
.
100/17 = 5.88 meters per second
A vertical line can only pass through the x axsis not the y unless it was at 0 then it would pass through all the y points. A diagonal line can pass through (-5,1) but not a vertical choose x=-5 if you want it to be a vertical line going through (-5,0)
D
is certainly wrong. You could extend the length of AD as far as you want and the two triangles (ABD and ACD) would still be congruent.
C
is wrong as well. The triangles might be similar, but they are more. They are congruent.
B
You don't have to prove that. It is given on the way the diagram is marked.
A
A is your answer. The two triangles are congruent by SAS
