A ladder 20m leans against an electric pole. if the ladder makes an angle of 60 degrees with the ground find the highest of the electric pole

10 metres

Step-by-step explanation:

Let the height at which ladder is leaning be h

Sin30°=h/20

1/2=h/20

h=10

h=10 metres

The ladder is at 10 metres height on the wall

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
