Hi I'm Anya! Today I will be travelling to 3 different countries and measuring famous architecture using Trig!
Find height of Big Ben clock tower in London!
So: tan60° = x/56 56(tan 60°) = x 96m = xBig Ben is 96m tall!
The tower makes a 60 degree angle with the ground.
We can use the tangent to find the height.
60°
56m
x
Let's find the height of the golden gate bridge!
So: cos40°=x/8888(cos40°)=x67m = x
We can use cosine to find the height (adj over hyp)
x m
40°
88m
Let's find the angle the Eiffel Tower makes with the ground!
We can use the inverse tangent to find the angle.
300m
75m
x°
So:tan-1(300/75) = x°75° = x°
Wow I went to London, San Francisco, AND Paris! It was so cool finding the height and angles of these structures using trigonometry. I'm so happy I learned this in Math class!
