In the figure a b c and d reflect across ef to coincides with points g j i and h respectively

∠GHI = 90° and coordinates of point K will be (8, -6)

Step-by-step explanation:

The given figure ABCD is reflected across EF to coincide with the points G, J, I and H.

We have to tell the measurement of ∠GHI. After reflection image formed by G,J,I and H will be similar.

Therefore ∠GHI = 90°

Now this figure GHIJ is reflected across x-axis then we have to find the coordinates of new point G.

Since point G(8, 6) is lying in the first quadrant, when reflected across x axis the new point K lies in 4th quadrant and the coordinates of K will be (8, -6).

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

this is not a question
