Answer:
80.02m
Step-by-step explanation:
Find the diagram attached. Using SOH, CAH, TOA to find the height of the cliff AC,
AC is the opposite side and BC is the adjacent
Given BC = 50m and ∠ABC = 58°
tan∠ABC = AC/BC
tan58° = AC/50
cross multiply
AC = 50tan58°
AC = 80.02m
Hence the height of the cliff is 80.02m

Answer:
The height of the cliff is 81.6m
Step-by-step explanation:
Please see the attachment below for an illustrative diagram representing the situation.
Step-by-step explanation:
From the diagram
x = /AB/
The height of the cliff is given by ( x + 1.6m)
Considering triangle ABC which is a right-angle triangle
/AB/ is the opposite and
/BC/ is the adjacent ; /BC/ = 50m
Angle of elevation is 58°
Then, we can write that
[tex]Tan 58^{o} = \frac{/AB/}{50m}[/tex]
[tex]/AB/ = 50 (tan58^{o})\\[/tex]
[tex]/AB/ = 50 \times 1.600[/tex]
[tex]/AB/ = 80.0m[/tex]
Hence, Side /AB/ = 80.0m
Since, /AB/ = x
∴ x = 80.0 m
Recall, the height of the cliff is given by
x + 1.6m
= 80.0m + 1.6m
= 81.6 m
Hence, the height of the cliff is 81.6m
