Question

Inclination of a ladder leaning against a wall is 30 degree and the foot of ladder is 2m away from the wall . Find the length of ladder​

Answer 1

Answer:

sin 30=2/x

1/2=2/x

x=4

therefore length of ladder is 4m

Step-by-step explanation:

Answer 2

Answer:

Let AC be a ladder, AB is the wall and BC is the ground as shown in the figure.

We know that

$\sf \: cos30 = \frac{bc}{ac } \\ \\ \sf \: \frac{1}{4} = \frac{2}{ac} \\ \\ \bf \: ac = 8m \\ \\ \bf so \: length of \: ladder \: is \: 8m$
