Step-by-step explanation:
angle 7 is corresponding to angle 1.
40 is 20% of 160, so if she saved 40$ and it was 20% off then the original price was 160$!!!
A. a=145 b=35 c=145 d=145 e=35 f=145 g=35
b. These are the pairs of vertical angles: a & c, b & 35, d & f, e & g.
Hope this was helpful.
P / 100 = 25 / 75;
p = 2500 / 75 ;
p = 33.33;
p% = 33.33%
