Solution:D

Hello!Even though the question on the wall is not entirely triangulation related, you need to understand the basic concepts of trigonometrical properties before you can actually carry out triangulation. So here is the working!

tan 71= x/100
x=295

See?Simple right!Taking the wall to be x, we take tangent(which is opposite over adjacent), and by estimation, we estimated the angle to be 71 degrees, hence tan 71, which will give us the answer x.

Thank you!:D

Wall length

HEY THERE!

Here's the wall picture that you might need to refer to. We took the base(length on the floor) as 100cm, the height of the wall is unknown, and so is the hypotenuse. If the angle between the hypo and the base is 71, what is the height? This is very much basic trigo properties, so it should be simple for you! This concept of trigonometry is how triangulation is used too:D

Theodolite!

Hello everyone!!


We're back again, but here with some information on something called a THEODOLITE!

Have you any idea what that is? Just a brief summary: A theodolite is an instrument for accurately measuring the horizontal and vertical angles, as used in triangulation networks. Well then, do you know how it looks like? This is how it looks like! 

We'll be carrying out measurements on another area in our school, the classroom wall!But unfortunately, we do not have the spending capacity to buy this instrument, so we will be estimating the height of the classroom through certain techniques. We'll be posting the wall picture and dimensions soon, so do take a look!


Thanks,
