Answer:
FCD
Step-by-step explanation: and sometimes we do not care about bold writing
FCD is the vertical angle I guess.
okay.
The question does not seem complete, but I'll represent the statement mathematically and look for their ages each. This is because the worst they can ask for is their ages.
Let C stand for Courtney's age, A for Andrei's age, N for Natalie's age and S for Shari's age. From the question we can deduce the following:
C = 2A
C = N + 3
C = S/2
S - N = C + A
S = 2C, N = C - 3 and A = C/2, therefore we have
2C - (C - 3) = C + C/2
C + 3 = C + C/2
C/2 = 3 and C = 6
A = C/2
A= 6/2
A = 3
N = C - 3
N = 6 - 3
N = 3
S = 2C
S = 2 x 6
S = 12.
C = 6, A = 3, N = 3 and S = 12

But you could also round it up to 29.
<u>Supplementary:</u> 1 and 2 & 3 and 4
Supplementary angles: A pair of angles whose sum is equal to 180°.
<u />
<u>Vertical:</u> 1 and 3 & 2 and 4
Vertical angles: A pair of opposite angles that are made by two intersecting lines.
<u>Complimentary:</u> None
Complimentary angles: A pair of angles whose sum is equal to 90°.
Hope this helps! :D
