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.
Replace the 'x' in the formula for g(x) by f(x):-
g(f(x)) = (x-7)^3
Its D
If we are dividing than it would be answer C because 8x2=16 and 16/2=8
Answer:
Step-by-step explanation:
hello :
you add 11² to complete the square
x²+22x+11²=50+11²
(x+11)² = 171
Answer:
No
Step-by-step explanation:
28*24=672. So, this is not even close to 800 and so isn’t reasonable.
