Answer:
180 Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.
Answer:
2 1/5
Step-by-step explanation:
2 3/4 divided by 1 2/4=2 1/5
Ok did your teacher say anything about not being able to use negative numbers or fractions? If not can you use fractions or negative numbers.
12x-5y=2
-5y=2-12x
y=-2/5+12/5x
should know the m=12/5
and (2,3) bring them to the line equation:
3=12/5x2+b
6/5+b=3
b=3-6/5
b=9/5
y=12/5x+9/5
Which means the answer is not in the choices.
