The base of a ladder is 6ft from the building and the angle formed by a ladder and the ground is 73 degrees

Length of ladder is 20.521 feet

Step-by-step explanation:

Given :The base of a ladder is 6 ft from the building and the angle formed by a ladder and the ground is 73 degrees

To Find : Length of ladder

Solution :

Refer the attached figure

The base of a ladder is 6 ft from the building i.e. CB = 6 feet

The angle formed by a ladder and the ground is 73 degrees i.e. ∠ACB = 73°

We are supposed to find the length of ladder i.e. AC

Hence Length of ladder is 20.521 feet

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
