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.

Step-by-step explanation:
Answer:
9 : 7
Step-by-step explanation:
Given
4.5 : 3 
( multiply both parts by 2 to clear the fractions )
= 9 : 7
The sum of the bottom interior angles is equal to the sum of the given exterior angles at the apex. (Both sums differ from 180° by the size of the interior apex angle.)
The angle labeled x is 51°.
Answer:
<h2>50.8</h2>
Step-by-step explanation:
sin x = 6.2/8
sin x = 0.775
x = 50. 8
