Answer:
CF
Step-by-step explanation:
we know that
An <u><em>angle bisector</em></u> is a line that divide an angle into two equal angles.
In this problem
---> given problem
---> by addition angle postulate
so
CF is an angle bisector of angle 
Answer:
Bridge = 300 m
Speed = 10 m/s
Step-by-step explanation:
If a goes past you in 10 seconds, it means the train has speed of
100 m/ 10 seconds as it is 100 m long
<u>The speed in m/s is:</u>
Then it take 3 times of 10 seconds to cross the bridge, so
<u>The length of the bridge is:</u>
Given:
The volume of the triangular prism = 27 cubic units
To find the volume of the prism if each side is dilated by 
Formula
The volume of a triangular prism

where, a be the height of the triangle
c be the base of the triangle
h be the height of the prism
Let us take after dilation the we get,

and

So,
After dilation the volume will be

or, 
or,
[Since,
]
or, 
Hence,
After dilation the volume of the prism will be 3 cubic unit.
Answer:

Step-by-step explanation:
Given
Options (a) to (d)
Required
Which represents an arrow pointing left
When an arrow points left on an inequality graph, the inequality is either of the following:
or 
From the given options (a) to (d), only
fits the above description.
Other options illustrate an arrow pointing to the right
To further explain this;
Looking at (b), we have:

This is rewritten as:
--- the same form as (c) and (d)
