1+4=5
2+5=7
5+7=12
3+6=9
12+9=21
I do not see21 up here so please cheek your question again or please change the 19 to a 21
First find a common denominator
1/16(2/2) = 2/32
9/32 - 2/32 = 7/32
7/32 is your answer
hope this helps
Since the two lines are parallel and it is cut by a transversal,
75+X+5=180
=>80+X=180
=>X=180-80
==>X=100
Hope this helps u...!!!!!
