PLEASEEEEEE HELP ME WITH THIS ONE ASAP PLEASE AND THANK YOU
Artemon [7]

Answer:

x=9 and z=83

Step-by-step explanation:

First you subtract 97 from 180 because that gives you z because 180 is a flat angle and 83 plus 97 gives 180. For x the opposite angle is also 97 so you set the equation 5x + 52 = 180 and you solve for x to get the x value. Hope this helps :)

If 5% of the total sale is 125 dollars what is the value of the ticket sale
RideAnS [48]
So the question is
:
5% of total sale is 125

'of' means mutiply
'is' means equals

percent means parts out of 100
5%=5/100=1/20
so now we have
1/20 times total sale=125
multiply both sides by 20 to clear fraction
20/20 times total sale=2500
1 times total sale=2500
total sale=2500
answer is total sale=$2500<span />
