Answer:
Regular hexagon =720
Regular octagon=1080
Step-by-step explanation:
The formula is (n-2) x 180, «n» is the side number of the polygon
The first one
So (n-2) x 180
(6-2) x 180
4 x 180
720
And the second polygon
(n-2)x 180
(8-2) x 180
6 x 180
1080
Answer:
When did Mary and Wyatt meet? 0.5 minutes later
How far from point Q did they meet? 3.5 km
Step-by-step explanation:
Mary’s motion is represented by d = 8t----(1)
Wyatt’s motion is represented by 2d + 14t = 15----(2)
We solve for d in equation (2) to get:d=7.5-7t----(3)
We equate equation (1) and (3) to get:
We now solve for t to get:
Now put t=0.5 into equation (1) to get d=0.5*8=4
This means they met 4 km from point P.
Therefore they meet 7.5-4=3.5km from point Q
Assuming the control tower is at sea level, the distance is 8463 feet.
