Thomas stood 12.0 m from the base of a tree. He used a clinometer to sight the top of the tree. The angle shown on the clinometer was 70°. Thomas held the clinometer 2.2 m about the ground. Determine the height of the tree to the nearest tenth of a metre.

Is it not an 'inclinometer' ?   Hmmmmm....

 

When we determine the height of the tree ...it will be from Thomas'  eyeballs....so we will add his height at the end

 

Draw a picture of the scenario for a clearer view:

 

Tan 70 = opp/adjacent  =   height / 12      

tan 70 = height / 12                 solve for height....then add Thomas height (2.2m ...Man!  He is TALLLLLLL!)
