A = 8
Step-by-step explanation:
Since Side BC and AD are equal
then we can plug both equations to each other to find A
6a + 20 = a + 60
solve it
6a + 20 = a + 60
- 20 -20
6a = a + 40
-a -a
5a = 40
a = 8
You can now find the length of all sides :)

For this case we have:
One hundred equals 100
three times fives equals![3 (5) = 15](/tpl/images/0179/9134/6ad43.png)
So, rewriting the expression we have:
One hundred divided by the quantity three times fives is equivalent to![\frac {20} {3}](/tpl/images/0179/9134/f8efa.png)
