Answer:
Option a.
Step-by-step explanation:
In the given triangle angle A is a right angle so triangle ABC is a right angled triangle.
Opposite side of right angle is hypotenuse. So, CB is hypotenuse.
From figure it is clear that CA is shorter that segment BA.
All angles are congruent to itself. So angle C is congruent to itself.
We know that, if an altitude is drawn from the right angle vertex in a right angle triangle it divide the triangle in two right angle triangles, then given triangle is similar to both new triangles.
So, triangle ABC is similar to triangle DBA if segment AD is an altitude of triangle ABC.
Therefore, the correct option is a.
 
        
             
        
        
        
Answer:
1 zero:  Answer C
Step-by-step explanation:
Keep in mind that the polynomial value is zero at any root.  Therefore each point that is a root must lie precisely on the x-axis (where y = 0).  In the graph given there is only one such point  (Answer C)
 
        
             
        
        
        
The first one [f(x) = 6x + 9] because “f(x) is y” and all you do is rearrange the equation
        
             
        
        
        
6.24 x 10^3.....^3, the 3 is the exponent
        
             
        
        
        
Use law of sine, sinB/AC=sinC/AB
sin122/10.2=sinC/6.8
sinC=sin122*6.8/10.2
