#### Storyboard Text

• Hey, I wonder what the height of this tree is. Let's use triginometry to solve this problem. ﻿
• Here I have an object called a clinometer. By looking through the straw towards the top of the tree, I am able to find the angle from the tree to myself by looking at the string touching the protractor.
• The angle is 45 degrees!﻿ This means it is a right angled triangle.
• 45﻿
• ﻿The next step is to find the distance between myself and the base of the tree.
• 550 cm
• The distance is 550 centimetres!﻿
• 180 cm
• The next step is to measure the distance from my eyes to the ground. It is 180 centimetres. ﻿
• x
• We now have formed a triangle with sides and angles, in which can provide us with the complete height of the tree.  The first step to this is finding x, with the following equation;
• 550 cm
• 45﻿
• 180 cm
• Then, we add the height of the distance from my eyes to the ground (180) and receive the overall height of the tree. Height of tree = 180 + 550 = 730 cm
• The equation that will help us find out the height of the tree is:﻿
