Complementary means they add to 90°
f=90-g
f=4g
4g =90-g
5g=90
g=18
f=4g=4(18)=72
Answer: f=72°, g=18°
Answer:
x^2 - 2x - 4
Step-by-step explanation:
g(x) - f(x) = (x^2 + 1) - (2x + 5) = x^2 + 1 - 2x -5 = x^2 -2x +(1-5) = x^2 - 2x - 4
C. Is your answer i think :)
Let's first get the representation of tan
We also need to understand how to convert radians to degrees

For question 1
since tan > 1
It must be in either first quadrant or third quadrant as shown in the diagram above
