We should find the height of this tree using our clinometer!
If we minus 90 from the reading, the angle of elevation would be 26 degrees
I am standing 30 metres from the tree, and i can see the top
Let's record our results and head home to do our math!
If we use tan theta equals o divided by a, substituting the results into the formula, the equation becomes tan 26 equals x divided by 30
We now times both sides of the equation by 30 to make x the subject, resulting in x equals 30 times tan 26
The answer is 35.36 to two decimal places. If we then add the height from the ground to my eyes to this number we know the height of the tree is 36.82 metres tall
