<h3>What is trigonometry?</h3>
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
The trigonometric function for an angle
is
![tan\theta = tan\dfrac{\pi}{4}=1\ \ \ \ Cos \theta=Cos\dfrac{\pi}{4}=\dfrac{\sqrt{2}}{2}\ \ \ \ Sin\theta =Sin\dfrac{\pi}{4}= \dfrac{\sqrt{2}}{2}](https://tex.z-dn.net/?f=tan%5Ctheta%20%3D%20tan%5Cdfrac%7B%5Cpi%7D%7B4%7D%3D1%5C%20%5C%20%5C%20%5C%20Cos%20%5Ctheta%3DCos%5Cdfrac%7B%5Cpi%7D%7B4%7D%3D%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D%5C%20%5C%20%5C%20%5C%20Sin%5Ctheta%20%3DSin%5Cdfrac%7B%5Cpi%7D%7B4%7D%3D%20%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D)
The trigonometric function for an angle
will be:-
![tan\theta=tan \dfrac{\pi}{6}= \dfrac{1}{\sqrt3}}\ \ \ \ \ Sin\theta =Sin\dfrac{\pi}{6}= \dfrac{1}{2} \ \ \ \ \ Cos \theta = Cos\dfrac{\pi}{6}= \dfrac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=tan%5Ctheta%3Dtan%20%5Cdfrac%7B%5Cpi%7D%7B6%7D%3D%20%5Cdfrac%7B1%7D%7B%5Csqrt3%7D%7D%5C%20%5C%20%5C%20%5C%20%5C%20Sin%5Ctheta%20%3DSin%5Cdfrac%7B%5Cpi%7D%7B6%7D%3D%20%5Cdfrac%7B1%7D%7B2%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%20Cos%20%5Ctheta%20%3D%20Cos%5Cdfrac%7B%5Cpi%7D%7B6%7D%3D%20%5Cdfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)

Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.
![7 \div 4 = 1.75](https://tex.z-dn.net/?f=7%20%5Cdiv%204%20%3D%201.75)
With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.
![6 \div 1.75 = 3.43](https://tex.z-dn.net/?f=6%20%5Cdiv%201.75%20%3D%203.43)
Answer : It'll take 3.43 hours to do the job if they work at the same rate.
Hope this helps. - M
