Answer:
x=10
Step-by-step explanation:
The lines the angles are on are 180 degrees so
(11x+23) + (7x-23)= 180
Let's rearrange them first
11x+7x + 23-23=180
Combine the like terms
18x + 0=180
Remove the 0
18x=180
Then divide 18 on each side
(y-p)/2
take p to the left side. + p becomes - p. Now divide the whole thing by 2
Answer: 249.75
Step-by-step explanation: 85% of 135 =114.75 +135=249.75
width = w
length = 2w
perimeter = 2w + 2 l
perimeter = 2w +2(2w)
60 = 2w + 4w
60= 6w
60=6w
w = 60/6 = 10
length = 10x2 = 20
10+10+20+20 = 60
100+20×12. ...............
the third one, c!
good luck
