Answer:

This is simple! (Kind of)

Step-by-step explanation:

First, notice how HJ is tangent. HG is a radius intersecting HJ at H.

This means, (According to some theorem that I forgot the name of) that GHJ is a right angle.

Thus, we can use the 180* in a triangle theorem.

$180=90+54+6x+6$

So, let's solve!

$30=6x\\5=x$

So, there you go! Nice and simple!

Hope this helps!

Find cos(1680°) and sin(1680°). Identify the measure of the reference angle.

s344n2d4d5 [400]

Answer:

Reference angle will be $60^{\circ}$

$cos(1680)=\frac{-1}{2}$

$sin(1680)=-0.866$

Step-by-step explanation:

We have given $cos(1680^{\circ})$

It can be written as $cos(1680^{\circ})=cos(8\pi +240)$

As 240° is lie in the third quadrant

And we know that for third quadrant

Reference angle is given by $angle-180^{\circ}$

So reference angle will be $240^{\circ}-180^{\circ}=60^{\circ}$

Now $cos(1640)=cos(9\pi +60)=-cos60=\frac{-1}{2}$

$sin(1640)=cos(9\pi +60)=-sin60=-0.866$
