Answer:
The value of f(3) is -2.
Step-by-step explanation:
This is a recursive function. So

Now, we find f(2) in function of f(1). So


Now, with f(2), we can find the value of f(3).


The value of f(3) is -2.

Answer:
∠ GDH = 67.5°
Step-by-step explanation:
The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
∠ GDH =
(GH + EF) =
(90 + 45)° = 0.5 × 135° = 67.5°
X=20
180=7x+x+20
-20. -20
180=7x+x
180=8x
divide by 8
x=20
