Answer:
![\angle G=20.8\approx 21^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20G%3D20.8%5Capprox%2021%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Given: In ΔGHI,
=90°, IG = 6.8 feet, and HI = 2.6 feet
To find: ![\angle G](https://tex.z-dn.net/?f=%5Cangle%20G)
Solution:
Trigonometry defines relationship between the sides and angles of the triangle.
For any angle
,
= side opposite to
/side adjacent to ![\theta](https://tex.z-dn.net/?f=%5Ctheta)
In ΔGHI,
![tan G=\frac{HI}{GI}](https://tex.z-dn.net/?f=tan%20G%3D%5Cfrac%7BHI%7D%7BGI%7D)
Put ![HI=2.6 \,\,feet\,,\,GI=6.8\,\,feet](https://tex.z-dn.net/?f=HI%3D2.6%20%20%5C%2C%5C%2Cfeet%5C%2C%2C%5C%2CGI%3D6.8%5C%2C%5C%2Cfeet)
So,
![tan G=\frac{2.6}{6.8}=0.38](https://tex.z-dn.net/?f=tan%20G%3D%5Cfrac%7B2.6%7D%7B6.8%7D%3D0.38)
Therefore, ![\angle G=20.8\approx 21^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20G%3D20.8%5Capprox%2021%5E%7B%5Ccirc%7D)
