Answer:
Step-by-step explanation:
standard form of fraction = -a/b
Example:
-4/2 = -2
4/-2 = -2
Take out the GCF of -4d, which creates
-4d(d^2+7d-1)
Doesn't seem right... tell me if I messed up anybody... if not, there's your answer.
Answer:
A) (i) a = 95° (180 - 85), b = 85° (180 - 95), c = 85° (180 - 95), d = 95° (180 - 85)
A) (ii) a = 103° (180 - 77), b = 77° (180 - 103), c = 103° (180 - 77), d = 77° (180 - 103)
B) (i) 95 + 85 + 85 + 95 = 360°
B (ii) 103 + 77 + 103 + 77 = 360°
Tip: Angles on a straight line add to 180°
Hope this helps!
