cos(3x) = cos(2x+x)
= cos(2x) cos (x) -sin(2x)sin(x)

Step-by-step explanation:

Answer:
61, 71, 83
Step-by-step explanation:
Step-by-step explanation:
To find unit rate
1 bag = 36÷ 3 = 12
So unit rate = $12
Answer:
The answer is 1/10
Step-by-step explanation:
Let us take the Shaded region be x
So,
2/5 + x = 1/2
Now, Solve for x
x + 2/5 = 1/2
5x + 2/5 = 1/2
2(5x + 2) = 5(1)
10x + 4 = 5
10x + 4 – 4 = 5 – 4
10x= 1
10x/10 = 1/10
x = 1/10
Thus, The value of x is 1/10
<h3>
<u>For</u><u> Verification</u>;</h3>
2/5 + x = 1/2
2/5 + 1/10 = 1/2
2 × 2/5 × 2 + 1/10 = 1/2
4/10 + 1/10 = 1/2
4 + 1/10 = 1/2
5/10 = 1/2
1/2 = 1/2
L.H.S = R.H.S
Hence Verified!
