Answer:
x = 3
Hope that helps!
Step-by-step explanation:
The percentage that it decreased/increased is 3.5%
If the value of y= 7
then next eqn is y= 2x + 1
substitute the value of y
7= 2x+1
7-1=2x
6=2x
6/2=x
3=x
anwser c.
multiply by 180 (n-2)
count how many sides you have.. subtract the sides by the number 2. then multiply tht by 180
Angle a,b,c equals 222; because angle a and b already is 180; so there is a right angle in the top with a 48 degree next to it so add then up and its 138; now subtract 180 which is the total of the total angels with 138 and you get 42; now add that to 180 and you get your answer which is 222.
