Step
Find the length side b of a square
Step
Find the length of the diagonal of a square
Applying the Pythagorean Theorem
therefore
the answer is
8-(4c-5)=11
Tell if the sequence is arithmetic, geometric or
neither: 5, 30, 180, 1080
Answer:
It is geometric
Step-by-step explanation:

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
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
Answer:
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
