Solving for Oblique Triangles # 2

Word Problem and Solution!

2. From the top of a building 60 ft high, the angle of elevation of a top of vertical pole is 14°. At the bottom of the building , the angle of elevation of the top of a pole is 28°. Find (a) the height of the pole and (b) the distance of the pole from the building

Note: all the illustrations were just approximates. The angles displayed may or may not be its actual measure.





Solving for Oblique Triangles

Here are some of the basic word problems that we encounter in studying trigonometry

Word Problem and Solution

Got Word Problems with your Trigonometry?

Just I decided to do something useful in here, I want you to help me help you! Believing in my confidence, I want to help you solve your trigonometric problems including word problems! Note: plane trigonometry only! I want us to do this together so if you have any idea or problems left unsolved, we will unravel the puzzle here.

Later, I will show you some of word problems in trigonometry with solutions. I have many in my notes and I will do the best I can to make it comprehensible. All the steps are included so just tell me if there is something that I am missing.

Most of the time we will be dealing with many right and oblique triangles here. Keep in touch. If you want to present a problem. just post it and we'll solve it.
