Mathematics

Answer:

Step-by-step explanation:

Sinθ = \frac{\text{Opposite side}}{\text{Hypotenuse}}

If, sinθ = -\frac{1}{2} and π < θ < \frac{3\pi }{2}

Since, sinθ is negative, angle θ will be in IIIrd quadrant.

And the measure of angle θ will be (180° + 30°)

θ = 210°

It's necessary to remember that tangent and cotangent of angle θ in quadrant III are positive.

Therefore, cos(210°) = -\frac{\sqrt{3} }{2}

tan(210°) = \frac{1}{\sqrt{3} }

csc(210°) = -\frac{1}{2}

sec(210°) = -\frac{2}{\sqrt{3} }

cot(210°) = √3

Ally has 4 times as many pencils as Anna Claire. They have 30 pencils in all. How many pencils does Ally have?
dexar [7]

T = 30

A = 4c

Vlad [161]
For problems like this we can use algebra to help us, the farenheight 6 hours ago was:
 (2xt)-6=-20
We have to balance the sides out, first we minus 6
2xt=-26
Now we can divide by 2
t=-13

We now know the temperature 6 hours ago was -13

Select the type of equations
olya-2409 [2.1K]
Two lines are "inconsistent" if they are parallel. They are "equivalent" if they are the same line. Otherwise, they are "consistent."

Your first 3 graphs show "consistent" equations.

The 4th graph shows "inconsistent" equations.

The solution shown on the 5th graph is where the lines intersect, near point
