Answer:

  cosine theta equals negative square root of three over two; tangent theta equals negative square root of three over three

Step-by-step explanation:

If the angle were a 1st-quadrant angle, it would be ...

  arcsin(1/2) = π/6

and the other functions would be ...

  cos(π/6) = (√3)/2

  tan(π/6) = 1/√3 = (√3)/3

__

The angle of interest is in the second quadrant, where the signs of cosine and tangent are negative. Hence, ...

  • θ = 5π/6
  • cos(5π/6) = -(√3)/2
  • tan(5π/6) = -(√3)/3

What is the slope of the line whose equation is -48 = 2x - 8y?<br> Enter your answer in the box.
aleksandr82 [10.1K]

Answer:

The slope is \frac{2}{8}

Step-by-step explanation:

Take the general equation of a straight line y = mx+c

Here m is the slope of the line.

So let's get the equation of the line in the question in the same form.

-48 = 2x-8y

Add 8y to both sides: 8y - 48 = 2x

Add 48 to both sides: 8y = 2x + 48

Divide by 8 to get it into the general equation: y = \frac{2}{8} x + 6

Now compare it to the general equation to find the value of m. The value of m is the coefficient of x which we can see is \frac{2}{8}

sesenic [268]
Hi!
We know that Mr. Abraham’s wife is 6 years younger than him, which is 36-6, which means his wife is 30 years old.

We also know that Mr A’s son is 24 years younger than his wife, which is 30-24, which is 6.

As of right now, we now know that:
Mr. A is 36
Mr. A’s wife is 30
Mr. A’s son is 6

It’s asking for the ratio of Him:Wife:Son, so 36:30:6.

BUT, it’s asking for simplest form, so divide each of those numbers by 6.

Your answer is: 6:5:1
