Answer:
Carlos is incorrect.
Step-by-step explanation:
We have been given that a line through the origin has a slope of  . Carlos thinks the slope of a perpendicular line at the origin will be 3.
. Carlos thinks the slope of a perpendicular line at the origin will be 3. 
We know that the slope of a perpendicular line to a given line is always negative reciprocal of the slope of the given line.
The slope of the perpendicular line at the origin will be negative reciprocal of  .
. 
Let us find negative reciprocal of  as:
 as:

Since the slope of a perpendicular line at the origin is  , therefore, Carlos is incorrect.
, therefore, Carlos is incorrect.
 
        
             
        
        
        
Answer:
   3)  16.2
Step-by-step explanation:
The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:
   CB/CD = CF/CA
   CB = CD·CF/CA = 7.2·21.6/9.6
   CB = 16.2
_____
When given two "point-to-point" triangles like this, quite often there is some sort of similarity relationship involved. First, you need to figure out what it is; then you need to make use of it as needed to answer the question being asked.
 
        
             
        
        
        
The answer is C), 834, 834.19, 834.2, 834.29
