HELP AND NO PEOPLE TELL ME THING I DONT' CARE FOR

103

Step-by-step explanation:

How would we know what you don't care for. We can't read your mind...

Visualize the triangle or draw it out.

The angle bisector means that the angle or side is split in half.

Draw a straight line splitting the angle in half and heading out on both A and B.

As the question said, it should intersect once somewhere.

That angle formed by the intersection is <m and you want the measurement.

If the angles are bisected, the degrees must be halfed.

You half the two angles.

You add the two angles.

There are 180 degrees in a triangle, so you subtract it from 180.

There you go.

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
