The solution of the sin (10x) cos (7x) is 1/2 sin(17x ) + sin(3x).
<h3>What are the trigonometric identities?</h3>
We can calculate with the help of one of the trigonometric identities;
sin(A)cos(B) = 1/2 sin(A+B) + sin(A - B)
WE have given
sin (10x) cos (7x)
Here, A = 10x
B= 7x
So, sin(A)cos(B) = 1/2 sin(A+B) + sin(A - B)
sin(10x) cos(7x) = 1/2 sin(10x + 7x ) + Sin (10x - 7x)
sin(10x) cos(7x) = 1/2 sin(17x ) + sin(3x)
sin(10x) cos(7x) = 1/2 sin(17x ) + sin(3x)

Answer:
3 sides
Step-by-step explanation:
Interior angle = {n - 2}{180/n}
60 = {n - 2}{180/n}
Cross multiply
60n = {n - 2}180
Dividing through by 60
n = (n - 2)3
n = 3n - 6
3n - n = 6
2n = 6
n = 6/2
n = 3
