Answer: (2α) = cos²(α) - sin²(α)
Step-by-step explanation:
The expression for cosine of the sum of two angles is:
cos (α + β) = cos(α)*cos(β) - sin(α)*sin(β)
in case α = β
cos ( α + α ) = cos (2α) = cos(α)*cos(α) - sin(α)*cos(α)
Hence cos (2α) = cos²(α) - sin²(α)
18 glasses of water
3.6/.2=18
Answer:
a) 1/36in.
b) 1/54in
Step-by-step explanation:
a) convert feet to inches:
L = 18ft = 216in
if length in image is 6in then 216in/6in. 36in is Scale.
width of original room = 108in.
check: 216*1/36 = 6
b) L = 18ft = 216in
216in/4in = 54in.
check: 216*1/54 = 4
