Answer:
Step-by-step explanation:
the side with the biggest angel across form it has the longest side
the unknown angle would be 180-50-20=110
so it would go 20,50,110
Answer:
y=2x+5
y=-1.5x+9
3y=-2x+10
Step-by-step explanation:
2x+y=5
y=2x+5
9-y=1.5x
-y=1.5-9
y=-1.5x-9
2x=-3y+10
3y=-2x+10
Answer:
9
Step-by-step explanation:
1. You would make these to equations equal to each other because there are parellel(they have the same angel)
2. EQUAL these 2 equations together to find r.
3. SOLVING for r
7r - 5 = 6r + 4
r = 9
Answer:
2160
