8 more than half of n is 8 + n/2. That is c.
So,
c = n/2 + 8
or c = 8 + n/2.
The answer is a.
hope this helps!! :)
Well, your ratio given is 18 to 4. so multiply both numbers (18 and 4) by some number and you will have an equivalent ratio.
example: if you had 2 times as many people, then an equivalent ratio would be 18*2 to 4*2 = 36 to 8
Answer:
ok first
follow me. ...........................
AC = √(40²-12²) = √(1600-144) = √1456 = 4√91
tanA = 12/4√91 = 3/√91 = 3√91/91
option а.
