The answer should be 12.2
7^2+10^2=c^2
49+100=c^2
149=c^2
12.2=c
4 and w. There are four “w”.
Answer:
sin ^2 x+ cos ^2 x = 1
Step-by-step explanation:
sin^2 x - cos ^2 x sin ^2 x = sin ^4 x
Factor sin^2 x
sin ^2 x ( 1- cos ^2 x ) = sin ^4 x
Using the identity sin ^2 x+ cos ^2 x = 1 written as 1 -cos ^2 x = sin ^2 x
sin ^2 x ( sin^2 x ) = sin ^4 x
sin ^4 x = sin ^4 x
The answer should be 390=60s, assuming s is the number of shelves he would need.
By the way, if you want the answer using this formula:
390=60s
390/60=s
6.5=s
s=6.5
