Describe the symmetry of these functions
Oduvanchick [21]
If it was line symmetry it would need to repeat the same shape twice, which the first follows but the second doesn’t.
if it was rotational, you would need to be able to take the shape in the top right and rotate it counterclockwise or clockwise to get the shape that locks in place. that doesn’t follow that.
both line and rotational symmetry is incorrect because the first example would need to lock up inside the right side of that example.

the answer is C

This is a question of proportions:

First we can work out how many feet it goes up for each feet he steps back:

5.5/6 ft per each feet he steps back.

Now we can multiply this by the amount of ft back the cliff is:

(5.5/6)*30 = 27.5 ft

Thus the cliff is 27.5 ft tall,

Hope this helps :)
