Answer:
a 2 cm and 6 cm
Step-by-step explanation:
The product of the dimensions must be 12 cm². (All answer choices meet that requirement.)
Opposite sides of a rectangle are the same length, so the sum of the two dimensions must be half the perimeter, 8 cm. The sums of the answer choices are ...
8 cm
7 cm
9.5 cm
13 cm
Only the first answer choice meets the requirement for a perimeter of 16 cm. The dimensions could be 2 cm and 6 cm.
Well, lets start with #3!
<1 is equivalent to <3 because they are vertical angles.
This means that <2 and <4 are congruent because they are vertical angles. We know that a straight line is 180 degrees. So, <1 and <2 added together will equal 180, therefore, <2 is ___________
Since the two lines are parallel, any angle on the other side is congruent, as long as that angle is in the same place as the other. So, we can see that <1 and <7 are in the same place, just moved down. So, <7 is __________.
Answer:
proportion:
0.8/100=1.5/x
by cross multiplication
0.8 x=150
x=187.5
his answer is reasonable.
