Answer:
Below in bold.
Step-by-step explanation:
b.
If we drop a perpendicular line from B to AC and mark the point D on AC, we have 2 right triangles, with AD = DC = 16 cm.
So tan O = BD/16 = 15/8
BD = (16*15)/8
= 2*15
= 30.
So the area of triangle ABC = 16*30
= 480 cm^2.
 
        
             
        
        
        
Answer:
123 ; 54 ; 1 ; 0.5 ; 0.03 ; 0 ; -1 ; -4 ; -10 ; -134
Step-by-step explanation:
123 ; 54 ; 1 ; 0.5 ; 0.03 ; 0 ; -1 ; -4 ; -10 ; -134
 
        
             
        
        
        
Answer:
y=4x-4
slope of the line=-4/-1
                              4/1
since perpendicular,
     m1.m2=-1
     4.m2=-1
     m2=-1/4 
The equation of line passing through the point (4,2)is
   y-y1=m2(x-x1)
   y-2=-1/4(x-4)
