Answer:
y = 55
Step-by-step explanation:
The sum of the angles of a triangle are 180
40 + y+30 + y = 180
Combine like terms
70 +2y = 180
Subtract 70 from each side
2y = 180-70
2y = 110
Divide each side by 2
2y/2 = 110/2
y = 55
1. Y=3/1+b
2. Y=-1/2+b
3. Y=-3/3+b
4. I can’t quiet remember how to do sorry :/
9/2+5/78
9/2+47/8
83/8
10 3/8
decimal form 10.375.
hope this helps!
Answer:
