Answers

Answer 1

Step-by-step explanation:

Given

[tex]f(x) = \frac{x + 5}{x} [/tex]

So

[tex]f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2} [/tex]

Now

[tex] {f}^{ - 1} (x) = \frac{5}{x - 1} [/tex]

So

[tex] {f}^{ - 1} (2) = \frac{5}{2 - 1} \\ = \frac{5}{ 1} \\ = 5[/tex]

Hope it will help :)❤

Answers

Answer:

A) AA similarity

Step-by-step explanation:

AA stands for "angle, angle" and means that the triangles have two of their angles equal.

SAS stands for "side, angle, side" and means that we have two triangles where the ratio between two sides is the same as the ratio between another two sides  and we we also know the included angles are equal.

SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.

Here we can easily see that two angles are equal

∠CYK and ∠KZP∠CKY and ∠PKZ (they're cross angles)

Therefore it's AA similarity
