The distance of the foot ladder can be given off by 1/2 hypotenus = 1 9 / 2 = 9 . 5 meters.This is true by the 3 0 , 6 0 , 9 0 special right trianlge.
Btw this should be in geometry section.
19 sin 30 *= 19/2= 9.5Write a solution.
Let the distance between the foot of the ladder and the wall be 'd'.
In a right-angled triangle: cosine = adjacent/hypotenuse
Therefore, cos(60) = d/19
d = 19 x 0.5
d = 9.5 metres
Leaning ladder makes a 90° angle, thus forms a right angled triangle, in which the length of ladder is the hypotenuse (19m), angle is 60° and we have to find base. Using trigonometry, cos 30 = x/19, on solving gives 9.5
Consider the Ladder to the wall makes a right angled triangle, then hypotenese = 19m adjacent = ?
cos 60 = adjacent / hypotenese 0.5 = adjacent / 19 therefore, swapping LHS and RHS adjacent = 19 x 0.5 adjacent = 9.5
done....
As angle is 60 deg at base-ladder meet point, hypotenuse is double the base always (By 30-60-90 theorem).
And now, hypotenuse is 19......that means base must be its half!!!!!
i.e. 9.5
Half of 19 is 9.5. Edit your solution @VAIBHAV borale
cos(60) x 19 gives the length of the distance between the base of the ladder and the base of the house
Let the angle made by ladder with the wall be Δ => Δ= 60° Lenth of ladder=19m
CosΔ=base / hypotenuse
Cos 60°= distance from wall/length of ladder
1/2=d/19
==> d= 9.5m

In triangle ABC,let the ladder be AB=19m and the distance of the foot of the ladder from the wall be AC=x. Now, cos60=x/19 so,x=9.5. That's our solution....
