The copper wire was 150 meters longer than the steel wire. You take 240-60 and get 180. You can then divide that number by 2 to figure out how long the steel wire was to get 90. From there, subtract the 90 by the original 240 and you’ll get 150.
If Perimeter is P=2l+2w then
2w=P-2l
therefore
w=(p-2l)/2
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there. So in other words no matter what way it is flipped or anything else that does not change the numbers on the sides it is congruent.
Answer:
The quotient will be -1
Step-by-step explanation:
2.6 ÷ -2.6
= 2.6/-2.6
= 1/-1
= -1
