The order of operations is PEMDAS (parenthesis, exponents, multiplication/division, addition/subtraction). This means that you do multiplication before adding, so 3 + 4*6 is the same thing as 3 + (4*6). Because of this, Omar did not need to use a grouping symbol.
These questions seems a little bit easy for me, I'm not really sure if it does or not.
(Also, do not forgot to put the degrees)
So the answers are:
1) point w=80, vertically opposite
2) 95+120+85+d=360
D=360-300
Point D= 60
3)65+87+110+G=360
G= 360-262
Point G=98
4) point L=90, the square is super easy
5) point L= 68
6) 90+86+114+V=360
V=360-290
Point V=70
(I put words instead of question mark)

Answer:
N = 3
Step-by-step explanation:
I don't know what the whole thing above is, but just disregard that.
All it is here is cross multiplication.
So 28N = 21 * 4
Multiply...
28N = 84
And divide each side by 28
N = 3
This is the number of combinations of 2 from 23
23C2 = 23! / 2! 21!
A quick way to do this is 23*22 / 2 = 253
