Answer:
Step-by-step explanation:
A associative property of multiplication
Because the perimeter is 20m, the short sides of the rectangle can be 2m and the long sides are 8m (since 2m + 2m + 8m + 8m = 20m)
And since we figured out 2 of the side lengths (2 and 8), we can figure out the area
2 x 8 = 16
Therefore, the area is 16m
Answer:2x3/5x4=6/20
Step-by-step explanation:
wait no it would be 4/15 the answer is 4/15\
Answer:
Angle number 5
Step-by-step explanation:
The sum of supplementary angles equal 180°.
Angle AED, in the diagram given is labelled angle 4.
The angle labelled 4 forms a linear pair with the angle labelled 5.
Since a linear pair of angles = 180°, therefore:
m<AED + m<AEI = 180°.
That is:
m<4 + m<5 = 180°.
Both angles are supplementary.
Therefore, angle number 5 is supplementary to angle AED.
