Answer

8kg

Explanation

3/4--------15

2/5-------x

cross multiplying

3/4×X = 2/5×15

3X/4 = 30/5

3X/4 = 6

cross multiplying

3X = 4×6

3X = 24

dividing bothsides by 3

3X /3 = 24/3

X = 8

therefore, the answer is 8 kg

Semenov [28]
It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs

4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft

Vf = Vci - Vesf

Vf = 125.600 - 7235

Vf = 118365 m3
