Step-by-step explanation:
(i)
Using cos(a - b) = cos a cos b + sin a sin b
= cos a cos b + 
cos a cos b = 
(ii)
Using cos(a + b) = cos a cos b - sin a sin b
cos(a + b) = 
(iii)
Using cot a = 
× 
= 3

No he is not .500, .50 and .5 are all the same number.
Answer:
Step-by-step explanation:
Answer:
11m + 4n
Step-by-step explanation:
when two numbers with the same variable are added together or subtracted the result is just the numbers added or subtracted. So you can add 6m and 5m to get 11m. and you can subtract 3n from 7n to get 4n
11m + 4n
G=38
Whenever you divide or multiply by one the number stays the same, therefore just take out all the xs and then solve the equation. I hope this helps!
