Answer:
A≈114.32
Step-by-step explanation:
Because it has more mass so with less mass it accelerates faster. That is newtons 2nd law of motion.
BC/DC = 8/3.2 = 2.5
AB/BD = 12.5/5 = 2.5
AC/BC = 20/8 = 2.5
Since the results are all 2.5, this means that the triangles are similar triangles.
The justification you would use is the SSS similarity theorem.
SSS = side side side
Answer:
576xxxycm
Step-by-step explanation:
1cm×12x×x+48xy=576xxxycm
Divide actual feet by scaled feet then multiply by scale inches:
20 feet / 4 = 5
5 x 1/2 = 2 1/2
12 feet / 4 = 3
3 x 1/2 = 1 1/2
Dimensions are 2 1/2 inches by 1 1/2 inches
