Answer:
Combine points A with C and A with B. Consider ΔABD and ΔACD:
1. AD is common side, then AD\cong AD;
2. CD\cong BD - given in the diagram;
3. \angle ADB\cong \angle ADC .
By SAS Postulate, \triangle ABD\cong \triangle ACD . Congruent triangles have congruent corresponding sides and congruent corresponding angles, so AC\cong AB .
From this proof you can see that correct choice is option D (In triangles ABD and ACD, two sides and an included angle are equal.)
Step-by-step explanation:
With these types of probe lens with no coefficient for x, all you have to do is find two number that multiply to be 12, and those same two numbers must add to be 7.
Answer: (x+3)(x+4) because 3 and 4 multiply to be 12 as well as add to be 7.
