Answer:
x=40 degrees
Step-by-step explanation:
there is 180 degrees in half a circle,and 180-100=80
and because there are 2 x values on either side you divide that 80 by 2 which gives you 40.
Add all 3 and you get 264 then divide by 3 and you get 88
Answer:
c. a: 4
b: 12
c: 9
4x² +12x+9=0
(2x+3)(2x+3)= 0
(2x+3)²=0 {square root both sides}
2x+3=0
2x=-3
x= -3/2
I think it's 34.5 (I need more letters so I'm typing this)
