Check the picture below.
notice that the triangle ADH, since the segment AL is an angle bisector, meaning it cuts the angle A in two equal halves, then the triangle ADH is only using half of A.
-3 is actually less than -1
it can't be equal because they are 2 different values
and it can't be greater than because if you place -3 and -1 in a number Line, -1 is closer to 0 which equals that -1 is greater than -3
The angle of the triangle would be 72
Step-by-step explanation:
Given:
and 
We can solve for f(x) by writing

Let 

Then


We know that f(0) = 0 so we can find the value for k:

Therefore,
