Answer:
Sec y = q/r
Step-by-step explanation:
Sin y = 7/q
tan y = 7/r
Mathematically cos y = sin y/tan y
But sec y = 1/cos y
So therefore sec y = tan y/sin y
So that would be ;
7/r divided by 7/q
= 7/r * q/7
= q/r

Answer:
![\frac{4\pi}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Cpi%7D%7B3%7D)
Step-by-step explanation:
The original questions is suppose an ant walks counterclockwise on a unit circle from the point (1,0) to the endpoint of the radius that forms an angle of 240 degrees with the positive horizontal axis.
To find the distance ant walked we find the arc length of the sector with central angle 240 degree and radius =1 (unit circle)
arc length of a sector =![\frac{centralangle}{360} \cdot 2\pi r](https://tex.z-dn.net/?f=%5Cfrac%7Bcentralangle%7D%7B360%7D%20%5Ccdot%202%5Cpi%20r)
arc length of a sector =![\frac{240}{360} \cdot 2\pi(1)](https://tex.z-dn.net/?f=%5Cfrac%7B240%7D%7B360%7D%20%5Ccdot%202%5Cpi%281%29)
arc length of a sector =![\frac{2}{3} \cdot 2\pi](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20%5Ccdot%202%5Cpi)
![\frac{4\pi}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Cpi%7D%7B3%7D)
x - y = 16
x^2 + x^2 = 130
----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108
