HELP!! What is the approximate measure of angle x in the triangle shown?

Alex Ar [27]

<h3>Answer: D) 130.5 degrees</h3>

=================================================

Work Shown:

$c^2 = a^2 + b^2 - 2*a*b*\cos(C)\\\\10^2 = 5^2 + 6^2 - 2*5*6*\cos(x)\\\\100 = 25 + 36 - 60*\cos(x)\\\\100 = 61 - 60*\cos(x)\\\\100 - 61 = - 60*\cos(x)\\\\39 = - 60*\cos(x)\\\\\cos(x) = \frac{39}{-60}\\\\\cos(x) = -0.65\\\\x = \arccos(-0.65)\\\\x \approx 130.5416\\\\x \approx 130.5\\\\$

Note: I used the law of cosines. Make sure your calculator is in degree mode.

Can someone help me with this

V125BC [204]

Answer: Period = 4

Amplitude = 3

<u>Step-by-step explanation:</u>

Period is the interval of one "cycle" before the pattern repeats.

If you notice that when x = 0, y = -4.

When does the pattern repeat (reach -4 again)?

Answer: when x = 4.

So the interval of one "cycle" is 4 units --> Period = 4.

$Amplitude=\dfrac{Max-Min}{2}=\dfrac{2-(-4)}{2}=\dfrac{6}{2}=\bold{\large\boxed{3}}$
