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 :)
Answer:
A
Step-by-step explanation:
The x- coordinate of each point ( the domain ) maps to exactly 1 unique y- coordinate ( the range).
This means the situation given represents a function → A
It would be D because both are positive and are square roots
It would be 49,009 because LA of a cone is height (50) times the radius (120) and that equals about 49,009.
11-2×48= 412. So the value of the expression is 412.
