diagonal is sqrt of (s^2 x 2)
8^2 = 64
64*2 = 128
sqrt(128) = 11.3137
round answer as needed
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
Answer:
DE = 1.2ft
Step-by-step explanation:
It's actually a lot easier for someone to just draw a diagram. I recommend it in the future!
This is a right-angle triangle, so I'm guessing it's Sohcahtoa.
cos23° = DE/1.3
DE = 1.3cos 23°
DE = 1.1966...
Rounded:
DE = 1.2
