<h3>Answer: K ' is at (1, 4)</h3>

Explanation:

Point K is located at (1, -4)

We use the rule that $(x,y) \to (x,-y)$ when reflecting over the x axis.

The x coordinate stays the same, but the y coordinate flips from positive to negative or vice versa.

Therefore, K(1,-4) will move to K ' (1, 4)

Which angles are complementary to each other?

Oksi-84 [34.3K]

Answer:

All apply

Step-by-step explanation:

Complementary angles are ones that total 90°. Here, we have two pairs of congruent angles such that each pair totals 90°. We can mix and match to find pairs of complementary angles.

less than 45°: BGC and EGF

more than 45°: AGB and DGE

A complementary pair will consist of one angle from the first list and one angle from the second list. There are 4 possible pairings, and all are shown as answer choices.

All of the choices apply.
