Answer: x=5

Step-by-step explanation:

ABC=ABD+CBD

ABD=CBD         ==> Because they're formed from a bisecting line, meaning the angle ABC is divided into two equal angles.

5x-10=2x+5

3x-10=5

3x=15

x=5

Which trigonometric functions are negative in the fourth (IV) quadrant?
anzhelika [568]
<h3>Answers are: sine, tangent, cosecant, cotangent</h3>

Explanation:

On the unit circle we have some point (x,y) such that x = cos(theta) and y = sin(theta). The sine corresponds to the y coordinate of the point on the circle. Quadrant IV is below the x axis which explains why sine is negative here, since y < 0 here.

Since sine is negative, so is cosecant as this is the reciprocal of sine

csc = 1/sin

In quadrant IV, cosine is positive as x > 0 here. So the ratio tan = sin/cos is going to be negative. We have a negative over a positive when we divide.

Because tangent is negative, so is cotangent.

The only positive functions in Q4 are cosine and secant, which is because sec = 1/cos.

2x-8=4(x+1). Solve for X please!
julsineya [31]

Answer:

-6 = x

Step-by-step explanation:

2x-8=4(x+1)

Distribute

2x -8 = 4x+4

Subtract 2x

2x-8-2x = 4x-2x+4

-8 = 2x+4

Subtract 4

-8-4 = 2x+4-4

-12 = 2x

Divide by 2

-12/2 = 2x/2

-6 = x

This will get you the expression x - 3

Now, divide this by 6.

This will get you the expression \frac{x - 3}{6}

So, the final expression from the steps is \frac{x - 3}{6}
