Answer:
x=26
Step-by-step explanation:
by definition of alternate exterior angle rule 8x -71 = 5x +7
What you want to do is get your X's on one side I recommend subtracting 5x so that you don't have to deal with negative values.
8x-5x-71=5x-5x+7
3x-71=7
add 71 to both sides the goal now is trying to get by itself
3x-71+71=7+71
3x=78
now divide both sides by 3
3x/3=78/3
x=26
First rounding off the both values..
Answer = 53300 * 600
= 31980000
%age error = [(53300*600 - 53320*599) / (53320*599) ]*100
=0.1%
2/15 since there are two cards out of 15
Hope this helped:)
