(SAT Prep) The perimeter of pentagon ABCDE is 30 in, AB = 7 in, BC = CD = 6 in, DE = 5 in. How many sides of the pentagon have equal length?
The answer is 3 sides of the pentagon are equal to 6
in because I guessed a few times on this rsm q and got it right
Answer: 3 sides of the pentagon, equal to 6.
30 - 24, add up all the sides and subtract by 30.
30 - 24, add up all the sides and subtract by 30.
30 - 24, add up all the sides and subtract by 30. 3 sides=6in
To determine how many sides of the pentagon have equal length, we need to examine the given measurements.
Let's go step by step:
1. The perimeter of the pentagon ABCDE is 30 inches.
2. We are given that AB = 7 inches, BC = CD = 6 inches, and DE = 5 inches.
To find how many sides have equal length, we need to compare the lengths of the sides to one another.
If we examine the given lengths, we see that AB = 7 inches is different from BC = CD = 6 inches, which are also equal to each other. However, DE = 5 inches is different from both AB and BC = CD.
Based on this information, we can deduce that only two sides of the pentagon have equal lengths, BC and CD.
Therefore, the answer is: Two sides of the pentagon, BC and CD, have equal length.
the four given sides sum to 24
so the 5th side is 6 ... 30 - 24
30-24=6
3 sides equal 6
thank you
You have 4 sides. Add 'em up and subtract from 30 to get the 5th side.
Now, how many are equal?
