Question

can I get help and explain this step by step​

Answer 1

Answer:

6.83m

Step-by-step explanation:

let height of tower be x

as angle of elevation is 45° the distance between tower and point A is also x through tan theeta

then,

total height of tower and poll is 5+x m

again use tan theeta

we get,

tan60=5+x/x

root3 =5+x/x

solving it we get x=6.38m
