Sanjana took her students of class X to an educational trip where they saw Red Fort. She told them about the history of Red Fort where she narrated that Red Fort or Lal Qila is a historic fort located in Old Delhi, India that served as the main residence of the Mughal Emperors. Emperor Shah Jahan commissioned construction of the Red Fort on 12 May 1638, when he decided to shift his capital from Agra to Delhi. She also included that the Red Fort is about 18 –33 m (59 –108 ft) high.

Answer:
45°, 10√3
Step-by-step explanation:
Given,red fort's maximum height= 33m
perpenducular=height=33m.
base = dist. from fort to students 33m
tan theta= perp./base
33 = 1
33
so,theta for value 1 is 45° .
hence the angle of elevation to the fort is 45°.
(ii) shadow casted by tower =30m=BASE
angle of inclination =30° of sun ray
tan theta = perp.
base
tan 30°= AB
BC
1 = AB
√3 30m
AB√3 = 30m
AB= 30 = 30×√3 (rationalising)
√3 √3×√3
30√3 = 10√3m
3
Hence height of the tower =10√3m
