• 42 degrees﻿
• 5.73m﻿
• 1.49 meters
• SOH-CAH-TOA﻿
• Opposite
• ﻿X
• 5.73m
• 42 degrees﻿
• Hypotenuse
• I used my clinometer to measure the angle of elevation.
• ﻿X
• Triangle Created ﻿
• 42 degrees﻿
• ﻿I then used a tape measure to measure how far from the tree I was standing and the distance from my eyes to the floor
• Tan ø= O/A Tan 42= x/5.73 5.73Tan42= X X= 5.159315174 Height of Tree= 5.159315174 + 1.49 Height of Tree= 6.649315174  = 6.6 meters to 1 decimal place
• ﻿I then worked out which trigonometric ratio to use, Sine, Cosine, or Tan. It was tan
• ﻿6.6 meters
• I then drew my triangle with the substituted numbers to find the height of the tree.﻿
• 5.73﻿
• I then completed the following calculation on my calculator to determine the height of the tree﻿
• ﻿Yay! We found the height of the tree!!!!
