Step-by-step explanation:
If the equation is 55 - 0, the answer is 55
Answer:
12. 14 - 9 = 5
13. 8 + 4 = 12
14. 28/7 = 4
15. 9 x 3 = 27
16. 4 x 20 = 80
17. 15 - 10 = 5
AAAAHHHHHHH!!!!! ha HA HA!!!!!!
angle 2 = 7x + 1 ( vertically opposite angles)
7x + 1 + 18x + 4 = 180° ( forming linear pair).
7x + 18x + 4 +1 = 180°
25x + 5 = 180°
25x = 180 - 5
25x = 175
x = 7°
angle 2 = 7(7)+ 1
= 50°
