Answer:
Angle C=35 degrees
Step-by-step explanation:
Angle C is an external angle. So, we can use the external angle theorem and get the equation
Angle C= 1/2(100-30)
Angle C=1/2(70)
35
<C = 1/2 (large arc - small arc)
<C = 1/2 (100-30)
=1/2(70)
= 35

f(g(x)) =f(x+1)=7(x+1)^2
f(x+1)=7.(x^2+2x+1)
f(x+1)=7x^2+14x+7
