<span>Out of the choices given, the biconditional that is not a good definition is "a ray is a bisector of an angle if an only it splits the angle into two angles. Hope this helps!</span>
For the 1st one i believe its Y=6
And the second one is Y=1
One shaded triangle has a base of 4.5 ft and a height of 9 ft, so its area is 0.5 * 4.5 * 9 = 20.25.
There are two such triangles, so the area of the shaded region is 40.5.
It is relations happy early thanksgiving
