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:
(15,-14)
Step-by-step explanation:
Given that,
The midpoint of FG is (6-4) and the corrdinates of F are (-3,6).
Let (x,y) be the coordinates of point G. Using mid point formula,

So, the coordinates of G are (15,-14).

Answer:hourly pay for the junior employee in dollars and cents=$10.25
Step-by-step explanation:
Step 1
Total amount senior employee is being paid = amount per hour x hours worked
= $14 × 16 = $224.00
Total amount of junior employee since he/ she collects $39.50 less than senior employee= $224.00 - $39.50
= $184.50
Step 2
hourly pay of junior colleague= Total pay of junior colleague/ Hours worked
=$184.50 / 18 hours
= $10.25 per hour
