Answer:
840 m
Step-by-step explanation:
Please refer to the attached photo.
In the attached photo, h is the height of the cliff.
The following data were obtained from the attached photo:
Opposite = h
Adjacent = 1200
θ = 35 °
The height, h of the cliff can be obtained by using the Tan ratio as follow:
Opposite = h
Adjacent = 1200
θ = 35 °
Tan θ = Opposite /Adjacent
Tan 35 = h/1200
Cross multiply
h = 1200 × Tan 35
h = 1200 × 0.7
h = 840 m
Therefore, the cliff is 840 m tall.
