Answer:
cos(m∠B) = 2√5/5
Step-by-step explanation:
Easiest way is to guess and check on this problem. When you take the cos(m∠B), you would get 6/3√5, rationalized to 2√5/5. That would be the correct answer.
Answer:
3,800 = 38 * 100
Step-by-step explanation:
3.8 * 100
= 380
38 * 100
= 3,800
There is no missing exponent or factor, it's just 3.8 needs to be multiplied by 10.
-10/5 or -8/4
You can make up an equation with the solution of -2 by multiplying -2 by any number ( for example -2 x 5 ) and then divide the result by the random factor you chose ( which would be 5 in this case )
