Step-by-step explanation:
D yes I think cause it show the straight line passing through
Given that,
An expression : 
To find,
The value of the above expression when e = 12 and f = 1/2
Solution,
We have,

Put e = 12 and f = 1/2
So,

So, the value of the above expression is 1.
Answer:
Follows are the solution to the given question:
Step-by-step explanation:
There are missing details, which is why its solution is as follows:
When an angle bisector points so, its two sides of the corner are equidistant. Its corner bisector of a triangle angle is a straight line splitting its angle into two congruent directions. In such a single point, calling its incentives, follow three-angle engineers are required of its three triangle angles.
