Answer:
7.8 x 10^-6 or 7.8E-6
Step-by-step explanation:
Answer:
11. Not enough information
12. You can say DB = DC by SAA congruence rule and CPCTC (Corresponding parts of congruent triangles are congruent)
Step-by-step explanation:
For 12, you can say ΔABD≅ΔACD because they have a side in common (AD) and they have 2 congruent angles. Thus, you can use the SAA congruence criterion. Then, you can use CPCTC (Corresponding parts of congruent triangles are congruent) to say that DB = DC.
Hope this helps :)
I am attaching a document showing the steps.
Answer:
8 is the correct answer because coefficient lies before Exponent. Exponent is variable
So 8 is the coefficient.
