Well u can't get division but division is the opposite of multiplication so if it was 12 divided by 2 it would be 6 because 6 times 2 is 12
Answer:
18°
Step-by-step explanation:
The law of cosines tells you ...
a² = b² + c² -2bc·cos(A)
Solve for cos(A) and fill in the numbers. Note that the value of cos(A) is very close to 1, so the angle will be fairly small. This by itself can steer you to the correct answer.
cos(A) = (b² +c² -a²)/(2bc) = (49 +100 -16)/(2·7·10) = 133/140
A = arccos(133/140) ≈ 18.2° ≈ 18°
Answer:
the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side.
The advantage of using exponential notation is that you won't have to keep writing a long number
For example, 40,000,000,000,000 would be tedious to write over again, but using exponential notation that number would be just 4 X 10^13.
Answer : C (24 - 6) ÷ 3
(almost 100% sure this is correct lol)
