Answer:
BC = 10.24
Step-by-step explanation:
You can use the Pythagoras theorem for this question
+ =
a = 8cm
b = ???
c = 13cm
We will solve for B (length BC)
+ =
+ =
Rearrange for b
= -
= 105
b =
b = 10.24
8%=0.08 and 100%=1 (100% represents the original weight in percentaje)
If x is the weight you can express: 1x-0.08x=15.1
solve for x: 0.92x=15.1
x= 15.1/0.92=16.1
The original weight was 16.41 ounces
The answer to your question, is 4 inches
hope this helps :D
