Question

i got answer as 732m was that correct?​

Answer 1

i think 73.2 m is the answer

Answer 2

Answer:

Step-by-step explanation:

tan30-100/db

1/√3 = 100/db

db=100√3 ⇒ 1

tan45°=100/bc

1=100/bc

bc=100 ⇒ 2

dc=db-bc

from 1 and 2

dc=100√3-100

dc=100(√3-1)

since √3=1.732

dc=100(1.732-1)

dc=100×0.732

dc=73.2m
