State if the triangles in each pair are similar. If so, State how you know they are similar and complete the similarity statemen
yuradex [85]

Answer:

Answer is option 2

Step-by-step explanation:

We know that Angle M = Angle G (given in diagram)

We also know that Angle L in triangle LMN is equal to Angle L in triangle LGH

As two angles are equal in both triangles they are similar.

But why is it Triangle LGH instead of Triangle HGL?

As we know M=G therefore they should be in the same place in the name Of the triangle. In triangle LMN M is in the middle therefore Angle G should also be in the middle

Use the function f(x)=x^2-8 find the inverse of f(x)
likoan [24]

Answer:


Step-by-step explanation:

let : y = x² - 8

calculate : x

x² = y + 8

x exist : y + 8 ≥ 0

x = √(y + 8)    or x =  - √(y + 8)

conclusion :

if : x ≥ 0    the inverse of f(x) is : g(x) = √(x + 8)

if : x ≤ 0    the inverse of f(x) is : h(x) =  - √(x + 8)
