sec ^6 A−tan ^6A=(1+tan ^2A−tan ^2 A)(1+tan ^4
A+2tan ^2 A+tan ^2 A+tan ^4 A+tan ^4 A)
sec ^6 A−tan ^6 A=1+3tan ^2 A+3tan ^4A
L.H.S. = R.H.S.
Hence proved

The two events that are disjoint or mutually exclusive is getting a head and a tail at the same time. It because if you are going to flip a coin the result can either be head or tail but not both. The value of the two events occurring at the same is 0.
Answer:
10
Step-by-step explanation:
12/20 = 6/x
Using cross products
12*x = 20*6
12x = 120
Divide by 12
12x/12 = 120/12
x = 10
