Answer:
A
Explanation:
For functions to be inverse, it must be true that f( g(x) ) = x and g( f(x) ) = x.
But for F( G(x) ), we have √( G(x) - 3 ) + 8
= √( (x+8)² - 3 - 3 ) + 8
= √( (x+8)² - 6 ) + 8
This -6 part should be cancelled out for functions to work out but we cannot do that, therefore F(x) and G(x) are not inverse.

Answer:
a. AA
b. no (sides are not proportional)
Step-by-step explanation:
a. Two angles are marked as congruent. The triangles are similar by the AA postulate.
__
b. The side ratios 6 : 8 : 11 and 15 : 20 : 33 are both in reduced form. They are clearly not identical, so sides are not proportional. The triangles are not similar.
