M5 is the same as m1 so it's 75°
Answer:
Idk too much brain hurt
Step-by-step explanation:
Answer:
Remember,
and the range of g must be in the domain of f.
a)


The domain of f(g(x)) and g(f(x)) is the set of reals.
b)


The domain of f(g(x)) is the set of nonnegative reals and the domain of g(f(x)) is the set of number such that 
c)


The domain of f(g(x)) is the set of reals except the 1 and the domain of g(f(x)) is the set of reals except the 1 and -1
d)


The domain of f(g(x)) is the set of reals except 2, and the domain of g(f(x)) is the set of reals except -1.
e)


The domain of f(g(x)) is the set of nonnegative reals except -3. The domain of g(f(x)) is the set of nonnegative reals except -2.
Hello,
Each side of a triangle is less than the sum of the 2 others sides;
x<8+12 ==>x<20
8<x+12 already realized
12<x+8==>x>4
So:
4<x<20 (i suppose that all the vertex are not on the same line)
