Answer:
f(3) = 6
Step-by-step explanation:
Using the recursive rule and f(1) = 10 , then
f(2) = f(1) - 2 = 10 - 2 = 8
f(3) = f(2) - 2 = 8 - 2 = 6
Answer: It would be A, B, and lastly E.
Answer:
(A) Complements of the same angle are congruent.
Step-by-step explanation:
Since, ∠CEF is complementary to ∠DCF, therefore
∠CEF+∠DCF=90° (1)
Also, ∠CEG=∠CEF+∠FEG
⇒90°=∠CEF+∠FEG (2)
Therefore, from(1) and (2), we get
∠CEF+∠DCF=90°
∠CEF+∠FEG=90°
Subtracting both the equations, we get
∠DCF-∠FEG=0
∠DCF=∠FEG.
Hence, ∠DCF≅∠FEG by the rule: Complements of the same angle are congruent.
Answer:
1.44 units²
Step-by-step explanation:
The angle for the big triangle is 60°, so the smaller triangle is 30°
so to find the base of the small triangle you can do tan 30 = X/2
so x is 2, which means that the base of the big triangle is 4.
The area of the big triangle is 1/2bh = 1/2(4)(2) = 4 = 6.93
Find hypotenuse (radius) using Pythagorean Theorem r = 4
The area of the piece of pie is 
= 8.37
8.37 - 6.93 = 1.44
