Answer:
A: Move the decimal one place to the left
Step-by-step explanation:
Examples:
20 / 10 = 2
2 / 10 = 0.2
0.2 / 10 = 0.02
0.02 / 10 = 0.002
Answer:
2.52
Step-by-step explanation:
5x + 15.5 = 28.1
subtract 15.5 from both sides
5x = 12.6
divide both sides by 5
x = 2.52
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.
Answer:
B and C
Step-by-step explanation:
