Answer: 3.25 m
Step-by-step explanation:
as a tangency and a radius make a right angle, we can use Pythagoras.
c² = a² + b²
(r + 2)² = r² + 3²
r² + 4r + 4 = r² + 9
4r = 5
r = 1.25 m
so the official is standing 1.25 + 2 = 3.25 m from the center of the circle
This makes sense as a standard discus throwing circle is 2.5 m dia.
Your answer is C!..........:)
Y = -x + 3 .… m = -1
y = 2x – 6 .… m = 2
Tan Ø = | m2 – m1 / 1 + m2m1 |
Tan Ø = | 2 – -1 / 1 + (2 x -1) |
Tan Ø = | 3 / -1 |
Tan Ø = | -3 |
Tan Ø = 3
Ø = tan^-1 ( 3 )
Ø = 71.5°
