Answer:
x+115=180 x=65
90+65+y=180 y=25
Step-by-step explanation:
Answer:
They are not commutative, because f(g(x)) and g(f(x) are not equal.
Step-by-step explanation:
In order for the composition of the functions to be commutative, we must have ...
f(g(x)) ≡ g(f(x))
for all values of x.
Here, we have f(g(x)) = 1 and g(f(x)) = 2. f(g(x)) and g(f(x)) are not equal, so the composition of the functions is not commutative.
Answer:
f(2)=0
Step-by-step explanation:
f(2)=2x-4
2(2)-4
4-4
0
It would be a A. parallelogram, B. Quadrilateral
Since angle 4 is across from angle 2 it is equal to it because they are called opposite or vertical angles which are always equal.
Angle 4 = 143 degrees.
Angles 1 and 2 are supplementary because they share one of the same lines. This means their angle values add up to 180 which is the angle measure of a line.
180 - 143 = 37
Angle 1 = 37 degrees.
Since angle 3 is across from angle 1 it is equal to it because they are called opposite or vertical angles which are always equal.
Angle 3 = 37 degrees.
I hope this helps!
