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°.
6.40x+9.90(154-x)=1230.90
Solve for x
X=84 for child
154-84=70 for adults
133 is the Answer bc that is a supplementary angle and supplementary angles always sum up to 180 hope this helps please mark brainliest

Answer:
C
Step-by-step explanation:
1/4+3/4+3/4= 7/4
Now, we need to express as a mixed number.
7/4 = (4+3)/4 = (4/4) + (3/4) = 1 + 3/4 = 1 3/4
Answer C.
