Substitute g(x) where x is in the definition of f(x).
f(g(x)) = -3(g(x))^2 - 1
f(g(x)) = -3(-5x)^2 - 1
= -3(25x^2) - 1
f(g(x)) = -75x^2 - 1
Only 1, as the angles have to add up to 180°
Answer:
120
Step-by-step explanation:
Answer:
The measures of supplementary angles add up to 180°
If two supplementary angles are adjacent, they form a 360° angle. ( or a linear pair )
....of the known angle from 180

Some common math techniques that are best to know generally
It's a matter of opinion really, but I would say true.
