Answer:
36°
Step-by-step explanation:
From the question,
The sum of the exterior angle of a polygon = 360
From the diagram. the polygon is Decagon
Note: A Decagon is a polygon with 10 sides.
number of sides = 10 .
The exterior angle of a regular polygon = sum of the exterior angle/number of sides.
Exterior angle = 360/10
Exterior angle = 36°
Hence the measure the single extrior angle = 36°
Answer:
x = 50
Step-by-step explanation:
Let x be the original number.
This question can be expressed as:
0.4x = 20
0.4 of the original number is 20.
Now, we can directly solve for x:
4x = 200
x = 50

Answer:
10 km/h
Step-by-step explanation:
First, convert 150 minutes to hours:
