Answer:
next should be 2250 if my math is correct
Solve the "f" function with substitute 4 and solve the "g" function with what we get for the "f" function.
f(4) = 2(8) + 3
f(4) = 16 + 3
f(4) = 19
g(19) = 4(19) - 1
g(19) = 76 - 1
g(19) = 75
Best of Luck!
Apply Pythagoras:
length = sqrt( (10--4)² + (6-3)² ) = sqrt(205)
I believe also 115 degrees bc they’re vertical angles
