The law of cosines is used for calculating one side of the triangle if the angle opposite to that side is given as well as the other sides. For this problem, we are given angle B. Therefore, the correct answer among the choices given is option 1 where a is equal to 5 and c is equal to 3.
4 packs of bottled water (35*4=140)
7 packs of candy bars (20*7=140)
The number 23.57 is 10 times larger than 2.357.
Answer:
In our case the least precise is the one with no decimal units, in our case 231 cm
Step-by-step explanation:
Perimeter=2(L+w)
where;
L=length=81.47 cm
W=width=34.2 cm
Replacing;
Perimeter=2(81.47+34.2)=231.34 cm
The most precise is the one with the highest decimal units, for example 231.34 in our case the least precise is the one with no decimal units, in our case 231
