Step-by-step explanation:
D because the angles add up to 90
A because both sets of angles add up to 180
Answer:
11. 16x +(9x+5)= 180
25x + 5 = 180
25x= 175
x= 7
If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.
112 + 4y= 180
4y = 68
y= 17
Step-by-step explanation:
12. 6x - 11 + 2x - 9= 180
8x - 20= 180
8x= 200
x= 25
6(25) - 11= 139
20y + 19 = 139
20y = 120
y=6
Let, the original price = x
x*20 /100 = 27
x = 2700/20 = 135
Original price was $135
I am pretty sure the answer is c. I hope this helps
