Question

The angle below is the image formed when a figure containing JKL is dilated by a

scale factor of 3. What is the measure of JKL?
L'
K'
J'
110°

Answer 1

110°

Explanation:

You want to know the measure of angle JKL if its dilation by a factor of 2/3 results in angle J'K'L' with measure 110°.

Dilation

Dilation multiplies lengths by the dilation scale factor, but has no effect on angles or orientation.

The measure of angle J'K'L' is the same as the measure of angle JKL.

Angle JKL measures 110°.
