Answer:
Draw a right triangle and name it ABC- C is your right angle. A is the angle above C and B is the angle on the side of C. AC=12 and CB=5, you have to find AB using the Pythagorean Theorem.
Step-by-step explanation:
Using the Pythagorean Theorem you say:
AB²=AC²+CB²
AB²=12²+5²
AB²=144+25
AB²=169
AB=√169
AB= 13

Answer:
$7.80
Step-by-step explanation:
Multiply 0.4 (that is 40%) by 13
It would be 5.2
So subtract 5.2 from $13.00
7.8
So the CD price would be $7.80 with a 40% discount
Hope this helps you :)
