Answer : Jeni's displacement from the starting point is, 111.8 meter.
Step-by-step explanation :
To calculate the Jeni's displacement from the starting point we are using Pythagoras theorem in ΔABC :
Given:
Side AB = 100 m
Side BC = 50 m
Now put all the values in the above expression, we get the value of side AC.
Thus, the Jeni's displacement from the starting point is, 111.8 meter.
Answer:
120°
Step-by-step explanation:
A sector of a circle is the portion or region of a circle enclosed by two radii and an arc. The perimeter of a the sector of a circle is given by the formula:
Perimeter of sector = + 2r
Where θ is the angle which forms the sector and r is the radius of the circle.
Given that Perimeter of sector = 57.32 cm, radius (r) = 14 cm, we can find the angle θ using:
Perimeter of sector = + 2r
