On the grid provided, draw the graph of y = 50x. Daudi was standing on a balcony. He observed a ball on the ground, 47 m from the foot of the building. The angle of depression of the ball from Daudi's position was 15°. Calculate the height from the ground to where Daudi was.

• For $x = 0.5$: $y = 50 \times 0.5 = 25$
• For $x = 2$: $y = 50 \times 2 = 100$

$(0,0)$, $(0.5, 25)$, $(1, 50)$, $(1.5, 75)$, and $(2, 100)$.

The line should pass through the origin $(0,0)$ and extend to the last plotted point $(2,100)$.

2. Calculating the height of Daudi's position.

• Horizontal distance from the foot of the building to the ball (adjacent side) = 47 m.
• Angle of depression = $35^\circ$. This is equal to the angle of elevation from the ball to Daudi's position.
• Height from the ground to Daudi's position (opposite side) = $H$.
