Answer:
8x+140=180
8x=40
x=5°
Step-by-step explanation:
Sum of angles in a straight line=180°
1. (x+3)(x+1)
2. (m+4)(m+8)
3. (r-2)(r-1)
4. (x-5)(x-1)
5. (x-7)(x-3)
6. (x-11)(x-11)
7. (t-6)(t+2)
8. (p-8)(p-8)
9. (x-1)(x-9)
10. (x+5)(x+1)
11. (a+9)(a-1)
12. (y-8)(y+1)
13. (x-3)(x+1)
14. (y+13)(y+1)
15. (m+5)(m+4)
16. (x+10)(x+2)
17. (a-12)(a-2)
18. (y+9)(y+2)
19. xy(x+2+y) i think
20. ab(a-4+4b)
21. xy(x+6-7y)
how many tries do you have?
I think its d because the proportion 6/4 and LM/6 cuz the smaller number is on the bottom? I dont know try it. how many tried do you have?
Its either d or b
7y=21
y=21/7
y=3 answer
