Area of a triangle = (½)*(base length)*(height; that is, "perpendicular height");
________________________________________________________
or: A = (½) * b * h ;
_________________________
Given: "b = 4.8 mm" ;
"h = (¾) * b = (¾)* (4.8 mm) = 3.6 mm ;
→ h = 3.6 mm ;
_____________________________________
→ A = (½) * b * h ;
= (½) * (4.8 mm) * (3.6 mm) ;
→ A = 8.64 mm² ; which is: Answer choice: [C] .

Answer:
can you take a better picture?
Step-by-step explanation:
Let mass of truck be t
mass of car A be a
and carB be b
so , a=2b-5
t=a+2135
putting a into t...
t=2b-5+2135
so, a+b+t=11350 ( putting all values)
2b-5+b+2b-5+2135=11350
so b=1845
a=3685
t=5820
so weight of Car A is 3685 lb
weight of Car B is 1845 lb
and truck is 5820 lb ......answers !!
