Which trig expression can be used to find the height on the tree where the top guy wire attaches if the base of the wire is four feet from the base?

The trigonometric expression that can be used to find the height of the tree where the top guy wire attaches is tan(45 + 30)
The height of the tree can be found using trigonometric ratios.
Therefore,
tan ∅ = opposite / adjacent
Hence,
for the higher wire
tan 75 = h / 4
4 tan 75 = h
This can be express as follows:
tan 75 = tan(45 + 30)
Hence,
4 × 3.73205080757 = 14.9282032303 ft = 14.9ft
Hence, the trigonometric expression that can be used to find the height of the tree where the top guy wire attaches is tan(45 + 30)
