Such a ray that divides an angle into two equal angles is called an angle bisector.

Likewise, two rays that divide an angle into three congruent angles are called angle trisectors. Figure %:

In short, no.

Tanθ=sinθ/cosθ<br><br> True or False

Sedbober [7]

If;
A = Adjacent
O = Opposite
H = Hypotenuse

Then,
Sin Ф = O/H
Cos Ф = A/H
Therefore,
(Sin Ф)/Cos Ф) = (O/H)/(A/H) = (O/H)*(H/A) = O/A

Now,
tan Ф = O/A ----

Therefore, it is true that
tan Ф = SinФ/CosФ

Combine like terms. What is a simpler form of each expression?<br> 30 - 5d - C + 3d

borishaifa [10]

30 - 5d - c + 3d

In this equation there are two numbers which have the letter d with them. These would be like terms.

You have -5d + 3d which equals -2d

The simplified form would be 30 -2d -c

Solve the system by graphing y=-4x-2 -2x+y=-2 Plot both lines and point of intersection by moving the dots to the correct locati

UkoKoshka [18]

Answer:

The point of intersection is (0,-2).

Step-by-step explanation:

Equation 1: $y=-4x-2$

Equation 2 : $-2x+y=-2$

Plot the lines on the graph

Refer the attached figure

Equation 1: $y=-4x-2 ---- Red$

Equation 2 : $-2x+y=-2 ---- Blue$

Point of intersection : A point where both the lines intersect is called point of intersection.

So, Both lines intersect at point (0,-2)

So, Point of intersection is (0,-2)

Hence The point of intersection is (0,-2).
