Answer:
AD = 2√10
Step-by-step explanation:
We're looking for the length AD.
To start, let's break off two smaller triangles from this large one: ΔBDA andΔADC. These triangles are <em>similar</em>: that is, all their interior angles are the equal. Since they're similar, the corresponding sides of these triangles will be in proportion to each other. That is to say, the <em>ratio </em>between corresponding sides will be equal. AD on the larger triangle corresponds to BD on the smaller one, and DC on the larger triangle corresponds to DA on the smaller one. Using this information, we can set up the ratio

AD and DA describe the same line segment, so we can replace DA with AD, and substituting BD = 5 and DC = 8 makes the equation

Cross multiplying gives us
, and taking the square root gives us our value for AD:

So our solution is AD = 2√10
48 quarters is $12
5 nickels is .25
5 pennies is .5
the total is $12.30
