4-19.

When she was younger, Mary had to look up at a $68º$ angle to see into her father’s eyes whenever she was standing $15$ inches away. How high above the flat ground were her father’s eyes if Mary’s eyes were $32$ inches above the ground? Homework Help ✎

Draw a diagram and think about the slope ratio.

The slope ratio for $68º\approx \frac{5}{2} = \frac{\Delta y}{\Delta x}$.
