Answer: 178
Step-by-step explanation:
18x13
234 area of white granite
8x7
56 area of blue granite
234-56 to find the area of the white granite
SinB = cosC = AC / BC = 8/10 = 4/5;
tgB = ctg C = AC/AB = 8/6 = 4/3, because we use T. Pitagora for calculating AB;
sinC = cosB = AB/ BC = 6/10 = 3/5;
tgC = ctgB = AB/ AC = 6/8 = 3/4.
This is Newtons second law of motion
Force = mass * acceleration
so here we have:-
10 = 10 * a
a = 1
its acceleration is 1 meter / sec^2.
The correct answer is 1:2
