Answer: ∠A= 
Step-by-step explanation:
Since we have given that
CD bisects m∠ACB,
⇒ m∠ACD= m∠DCB =x (say)
And, AB=BC, m∠BEC=90°, and m∠DCE=42°
So,
m∠CAD=m∠ACD
In ΔDCE,

Now, in ΔACD,

Hence , ∠A= 
The GCF of these terms is 2.
Factors of 2: 1 and 2
Factors of 14: 1, 2, 7, and 14
Factors of 20: 1, 2, 4, 5, 10, and 20
They all have 2 in common.
Answer:D
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
A solution is (-1,4) means that point of intercept is (-1,4)
<=> when x=-1 so y = 4 for both equations
From the 4 possible answers, only graph D meets the requirement.
Hope it will find you well
