ok please do it ggggggggggghhh

Answer 1

Answer:

7 (1+√3) = 19.12 m

Step-by-step explanation:

1 .    distance of tower from building =  B

tan 45° = Height of building / distance of tower from building

   1 = 7 / B

B = 7 m

distance of tower from building is same at top and bottom of tower

tan 60 = (Height of tower above building)/distance of tower from building

Height of tower above building + Building height = tower height

= 7 + T     where T = tower height above building

Tan 60 = T / 7

√3 = T/7

T = 7√3

Tower height = 7 + 7√3 = 7 (1+√3)
