Question

From the top of a building 20 meter high, the angle of elevation of the top of
a vertical pole is 30° . and the angle of Jepression of the foot of the same pole
is 60°. Find the height of the pole​

Answer 1

height of the pole = 80m

Step-by-step explanation:

tan 60 = de /dc

dc =20

so √3 = de/20

so de = 20 √3

now de = bc = 20 √3

tan 60 = ab / bc

√3 = ab/20√3

so ab = 20 * 3 =60

ae = ab+be = 60 + 20  = 80 m
