Challenge Problems
Push your limits with advanced challenges
A building casts a shadow that is three times as long as its height when the sun is at an angle of 30°. How tall is the building?
💡 Hint: Set up the relationship using tangent.
If a tree measures 8 m tall and casts a 4 m shadow when the angle of elevation is 60°, find the angle of elevation when it casts an 8 m shadow.
💡 Hint: Consider the tree's height against the shadow’s length.
