Two buildings are facing each other on a road of width 12 metre . From the top of the first building, which is 10 metre high , the angle of elevation of the top of the second is found to be 60°. What is the height of the second building ? So easy question
Can u people solve ?
I dont think so

metres

Step-by-step explanation:

You are finding the height of the building with an angle of elevation, therefore we need to solve for EC to add it to BA [10 metres] and use TRIGONOMETRIC RATIOS to arrive at our conclusion. Just in case you have forgotten what they were, here they are:

We can now solve for EC:

OR

Now that you have solved for EC, you can now add it to your original 10 metres to get metres. As a decimal, you would get metres. You can go ahead and round this off if necessary.

** The reason why the cotangent [or tangent] ratio was used was because EA is equivalent to DB by the definition of a rectangle. It has two pairs of parallel and congruent sides with four right angles. Plus, that is the adjacent side of the triangle, while EC is the opposite side of the triangle, so we knew our ratios were correct.

I am joyous to assist you at any time.
