Answer:

63.5

Step-by-step explanation:

they all form a triangle, and the formula for that is a²+b²=c²

a=96       b=wire        c=72

96²+b²=72²

9216+b²=5184

-9216        -9216

b²= -4032

square root of -4032 = 63.5

Gino used 3/4 of the nails in a box. He has 16 nails left. How many did he use?
Irina18 [472]
Gino used 48 nails

If you take 16 and times it by 4, you get 64, you times it by four to get 4/4 which is the whole nail box. So 64-16 is 48 which is then 3/4 of the nail box.

Prove : Cos^4A+sin^4A=1/4(3+cos4A)
Talja [164]

Answer:

1 = (sin^2 A + cos^2 A)^2 = sin^4 A + cos^4 A + 2 sin^2 A cos^2 A

so

sin^4 A + cos^4 A

= 1 - 1/2 sin^2 2A

= 1 - 1/4 (1- cos 4A)

= 1/4 (3+cos 4A)
