Answer:
The coordinates of E are .
Step-by-step explanation:
The triangle ABC represents a right triangle as both sides AB and AC are orthogonal to each other. The side AB is in the y axis, whereas the side AC is in the x axis. The triangle is dilated with respect to the origin, in which point A is set.
Vectorially speaking, dilation is defined by the following operation:
(1)
Where:
- Point of reference.
- Original point.
- Dilated point.
- Dilation factor.
By applying this operation, point B becomes point D:
,
Lastly, we transform point C into point E by applying the same operation: ,
and
The coordinates of E are .
I believe the coordinates of K are
the x is negative and the y is positive because it's on the second quadrant.
y = because it is closer to half than
is
