Question

4) From one side of 'w' meters width of road, a man observes a top of 'h' meters height
building, which is another side of the road, with 450 of angle of elevation.
Then the relation between 'w' and 'h' is ​

Answer 1

Answer:

hey here is ur answer

please do refer to reference diagram which is uploaded in above pic

here we go

Step-by-step explanation:

so now width is represented by bc which is w metres broad

moreover ab represents height h

now angle acb is angle of elevation

therefore angle acb=45

now then we know that

tan=opposite side/adjacent side

so similarly tan c=ab upon bc

now angle c=45 ( given)

so tan 45=ab/bc

therefore

tan 45=1

so 1=ab/bc

now just cross multiply our answer is ready champ

therefore ab=bc

I hope u cracked the logic now
