Given :
A pipe can make with the horizontal. the minimum angle being 1/4 inch the maximum angle being 1/2 inch .
To Find :
The minimum and maximum angles to the nearest tenth of a degree that a pipe can make with the horizontal.
Solution :
Angle
is given by :
![tan\ \theta=(opp)/(adj)](https://img.qammunity.org/2021/formulas/mathematics/college/bn27n8jk1htuwzktpy2av3tpgqhul28e00.png)
Now , minimum angle is given by :
![tan\ \theta_(min)=((1)/(4))/(12)=0.02\\\\\theta_(min)=tan^(-1)(0.02)\\\\\theta_(min)=1.146^o](https://img.qammunity.org/2021/formulas/mathematics/college/79cqezcx78s4q94n0d0cf4oithzfm417rt.png)
For maximum angle :
![tan\ \theta_(max)=((1)/(2))/(12)=0.04\\\\\theta_(max)=tan^(-1)(0.04)\\\\\theta_(max)=2.291^o](https://img.qammunity.org/2021/formulas/mathematics/college/lvighyh90rpb31w5jdg48yhxkk3m1niyx7.png)
Therefore , minimum and maximum angle is 1.146° and 2.291° respectively .
Hence , this is the required solution .
