Dana made 96 strides.
Step-by-step explanation:
Given,
Ratio of Sally's stride to Dana's strides = 5:4
Strides made by Sally = 120
Let,
x be the strides made by Dana.
Ratio of Sally to Dana = 120:x
Using proportion;
Ratio of Sally's stride to Dana's stride :: Ratio of Sally to Dana

Product of mean = Product of extreme

Dividing both sides by 5

Dana made 96 strides.

We can see that
there are six sides
so, n=6
so, firstly we will find total angle
total angle =(n-2)*180
total angle =(6-2)*180
total angle =720
so, sum of all angles must be 720
so, we get

now, we can solve for x
