The angle of elevation of the sun is 68° when a tree casts a shadow 14.3 m long. How tall is the tree, to the nearest tenth of a meter?
Just like the girl one you posted earlier
Adjacent side is the shadow 14.3
Opposite side is the height
Tan 68 = opposite / adjacent
tan 68 = height / 14.3 Now use your calculator to find tan 68 then multiply by 14.3 m for your answer....height=.......m
