If AB is the same length as CD, BC is 2 cm shorter than AB and BE is 7 cm in length, find the length of AB.
does it involve any figure? if there is none, i think there is some info missing,, like what is the relation of BE to other segments/sides (or where is E located), something like that~
To find the length of AB, we need to use the information given in the question. Let's break it down step by step:
1. We know that AB is the same length as CD.
2. We also know that BC is 2 cm shorter than AB. So, the length of BC can be calculated by subtracting 2 cm from the length of AB.
3. Finally, we are given that BE is 7 cm in length, which means that BE can be added to the length of BC to get the length of AB.
Let's set up an equation to solve for AB:
AB = CD
BC = AB - 2
AB = BC + BE
Now, substitute the value of BC in the third equation using the value of AB from the first equation:
AB = (AB - 2) + 7
Simplifying the equation:
AB = AB + 5
Subtracting AB from both sides:
0 = 5
