Can you give the data please?
This would simplify to 6.60 meters/second.
The two angles given are vertical angles which mean they are the same.
x +40 = 60
Subtract 40 from both sides:
x = 20
Answer:
1080°
Step-by-step explanation:
formula to find the sum of interior angles of a polygon is (n-2)×180
octagon has 8 sides so n=8
(8-2)×180
6×180
=1080°
