This week in math 10 we learned about finding angles in right triangles and how they are relevant in everyday life, triangles can be found everywhere and can help you find nights and measurements. Triangles that are not “right triangles” have smaller right triangles inside of them, by using these you can find lengths of other objects. We can determine the sides of one triangle by using the other sides attached to it. 

This can be helpful if you can’t measure something, for example, a tree is very tall and you don’t have the means to measure its high, you can use the shadow of the tree and the angle to find the height of the tree. 

Most phones come with a measuring app, you can use this to find the angle of elevation:

Once you find this, one must measure the shadow of the tree:

When you have found these two thing use “Tangent” to determine the missing side (the height of the tree)

Trigonometry can be used everywhere with everything, to find angles and sides.
