A few years​ ago, a total of 2669 thousand people lived in the metropolitan areas of Las​ Vegas, Nevada, and​ Sacramento, Califo
aniked [119]
Let's make equation for this problem. Let's say the population of LV is x, then Sacramento will be x+275 since <span>Sacramento had 275 thousand more residents than Las Vegas. Remember that their total population is 2669, so your equation will be </span>x+275 +x=2669 

If you solve this equation, you have x=1197, that is population of LV. So Sacramento is 1472.

Algebra 2: PLEASE HELP ME!!
vfiekz [6]

Looks more like Trig than Algebra II

They want us to apply the sum angle formula to \sin(x + \frac{5 \pi}{6})

5π/6 is 150°; I find it easier to think in degrees.

When the tangent of x is 3/4 that's a right triangle with opposite 3, adjacent 4 so hypotenuse 5. So a sine of 3/5 and a cosine of 4/5, both positive because we're told x is in the first quadrant.

The sine sum angle formula is

\sin(a+b) = \sin a \cos b + \cos a \sin b

\sin(x+\frac{5\pi}{6}) = \sin x  \cos \frac{5\pi}{6} + \cos x \sin \frac{5\pi}{6}

We know sin 150° = sin 30° = 1/2 and cos 150° = - cos 30° = -√3/2

\sin(x+\frac{5\pi}{6}) = \frac 3 5  (- \sqrt{3}/2)  + \frac 4 5 (1/2)

\sin(x+\frac{5\pi}{6}) = \dfrac{ 4- 3\sqrt{3}}{10}

Third choice

What is the value of x ??
Finger [1]

Answer:

25

Step-by-step explanation:

180-45=135 and 180-135=45

360 is the sum of all angles so:

360-105-135-45=75

3x=75

x=25
