  2. Angle of Elevation 30o 80 m Draw the sketches illustrated in order to find the heights in the following exercise The angle of elevation to the top of the tree is 30o. Use a scale of 1 cm to 10 m to make a scale drawing. What is the height of the tree?

  3. 5 m Draw the sketches illustrated in order to find the heights in the following exercise Use a scale drawing to find the height of the signpost, shown below. The angle of elevation is 39o and the scale is 1 cm to 1 m.

  4. ? 15o 45 m Draw the sketches illustrated in order to find the heights in the following exercise If the angle of elevation is 15o, what should be the height of the town house? Use a scale of 1 cm to 5 m for a scale drawing.

  5. ? 15o 1 m 15 m Draw the sketches illustrated in order to find the heights in the following exercise David sees the traffic light hanging above the road at an angle of elevation of 15o. David is 15 m away from the traffic light. Use a scale of 1 cm to 3 m for a scale drawing. Find the height of the traffic light, but remember to add the height at which David is seating on the car.
