Answer:
<em> n = 13 </em>
Step-by-step explanation:
= 
+ (n - 1)d
= 3 + 7(n - 1) (for the first AP)
= 63 + 2(n - 1) ( for the second one)
3 + 7(n - 1) = 63 + 2(n - 1)
3 + 7n - 7 = 63 + 2n - 2
5n = 65
<em>n = 13</em>
Start with x:
Since x and 57º make a straight line, x+57 = 180 (because a line is 180º). This says x=123º
Now for y:
Because lines m and n are parallel, y and 57º are alternate interior angles and have the same measure. y=57º
Finish with z:
Since y and z make a straight line, can you finish that one from here?
DE=FG
40=x+5
35=x
x=35
The value of x is 35
