Answer:
∠DCF = 129°
Step-by-step explanation:
We assume that line CE is between lines CD and CF.
The angle sum theorem applies:
∠DCF = ∠DCE +∠ECF
∠DCF = 75° +54°
∠DCF = 129°
6/7 because 48 divided by 8 is 6 and 56 divided by 8 is 7
56* angles scale regardless of size 90* @ 9mmx9mm is still 90* in 9kmx9km
Answer: Its little bit hard to become tutor. You need to give more answers.
Step-by-step explanation:
Answer:
FALSE
Step-by-step explanation:
<E in ∆AED ≅ <E in ∆CEB.
Both are 90°.
Side ED ≅ Side EB
Side AD ≅ Side CB.
Thus, two sides (ED and AD) and a non-included angle (<E) of ∆AED are congruent to corresponding two sides (EB and CB) and a non-included angle (<E) of ∆CEB. Therefore, by A-S-S Congruence Theorem, both triangles are congruent to each other not by SSS.
