- 4. OBJECTIVE To measure the height of a real-life structure Light
- 5. FORMULAE Tan X° = Opp Adj Hypotenuse (Hyp) Adjacent (Adj) Opposite (Opp)
- 6. CALCULATION
- 7. AHMAD Angle = 48º Distance = 439 cm Eye level = 152 cm Tan 48° = 439 Eye Adj Level (height) Adj = 439 Tan 48º = 395.28 cm Therefore: total height = 395.28 +152 = 547.28 cm Distance
- 8. ANIYAH Angle = 40º Distance = 340 cm Eye level = 142 cm Tan 40° = 340 Eye Adj Level (height) Adj = 340 Tan 40º = 405.20 cm Therefore: total height = 405.20 +142 Distance = 547.20 cm
- 9. RAHMAN Angle = 33º Distance = 254 cm Eye level = 156 cm Tan 33° = 254 Adj Eye Adj = 254 Level Tan 33º (height) = 391.12 cm Therefore: total height = 391.12 +156 Distance = 547.12 cm
- 10. HAZWAN Angle = 28º Distance = 208 cm Eye level = 156 cm Tan 28° = 208 Eye Adj Level (height) Adj = 208 Tan 28º = 391.19 cm Therefore: total height Distance = 391.19 +156 = 547.19 cm
- 11. COMPARISON Total Height = 5.47m Height of the Light Ahmad Aniyah Rahman Hazwan Distance 439 340 254 208
Editor's Notes
- #4: 1. What is clinometer?Is an instrumentMeasure the angle of an inclination or slope2. The things that is needed to make clinometer:-Drinking strawTapeProtractorStringMass about 5 to 10 gram so we using rubber for the weight3. This is the picture of the clinometer that we make.
- #5: to measure real-life structure by using clinometer with different distances with the same height of object.
