Answer:

the value of x = 56

Step-by-step explanation:

if both are similar figures, then ratio of their

sides will be constant , so

=》14 / 17 = x / 68

=》14 / 17 × 68 = x

=》14 × 4 = x

=》x = 56

hence, value of x = 56.

i hope you got it.

Rewrite sin (6x) sin (x) as a sum or difference.

Ket [755]

Recall that

$\cos(x\pm y)=\cos x\cos y\mp\sin x\sin y$

It follows that

$\sin x\sin y=\dfrac{\cos(x-y)-\cos(x+y)}2$

Replace $y$ with $6x$ and you get

$\sin6x\sin x=\dfrac{\cos(x-6x)-\cos(x+6x)}2=\dfrac{\cos5x-\cos7x}2$

(using the fact that $\cos(-5x)=\cos5x$ )
