Answer:

see explanation

Step-by-step explanation:

Using the Addition formula for sine

sin(x ± y) = sinxcosy ± cosxsiny

Consider the left side

sin(360 - Θ ), then

= sin360°cosΘ - cos360°sinΘ

= 0 × cosΘ - 1 × sinΘ

= 0 - sinΘ = - sinΘ → verified

Answer:  sin(360\°-\theta)=-sin\theta is TRUE (See the explanation)

Step-by-step explanation:

To verify sin(360\°-\theta)=-sin\theta you need to use the following identity:

sin(x\±y)=sin(x)\ cos(y)\±cos(x)\ sin(y)

It is important to know that:

sin(360\°)=0\\\\cos(360\°)=1

Then, knowing this, you get:

sin(360\°-\theta)=sin(360\°)\ cos\theta-cos(360\°)\ sin\theta=0\ cos\theta-1\ sin\theta=-sin\theta

Therefore sin(360\°-\theta)=-sin\theta is TRUE.

The measure of each interior angle of a regular polygon is 157.5 ∘ . How many sides does the polygon have?
uranmaximum [27]

180(n-2)=157.5n

180N-360=157.5n

180N-157.5n=360

22.5N=360

N=360/22.5

N=16
