Answer:
x = 10°, y = 20°
Step-by-step explanation:
Fill in the missing angle measures, 20° and 70°.
7x = 180 - 90 - 20
7x = 70
x = 10
2y = 180 - 7x - 5x - 20 = 40
y = 20
Given:
The graph of two function f(x) and g(x).
To find:
The value of f(4) and the value of x if g(x)=2.
Solution:
In the given graph red curve is the graph of f(x) and the blue curve is the graph of g(x).
From the given graph it is clear that the value of the function f(x) at x=4 is -10. So,

From the given graph, it is clear that the value of function g(x) is 2 at x=0. So,

Therefore, the value for the first blank is -10 and the value for the second blank is 0.
the correct answer is c 78
Step-by-step explanation:
lit can't be a because to small and can't be b because also to small. and and 92 is uptus and this is an acute angle
Answer:

Step-by-step explanation:
f(x)=x²-1
g(x)= x+2
f(g(x)) =f(x+2)
=(x+2)²-1
=x²+4x+4-1
=x²+4x+3
It is the first option . A is correct
