Apainter leans a 34-ft ladder against a building. the base of the ladder is 16 ft from the building. to the nearest foot, how high on the building does the ladder reach?
a) 30 feet
b) 38 feet
c) 26 feet
d) 18 feet

The height reached by ladder on the building is 30 ft.

Step-by-step explanation:

Let x be the height reached by ladder on the building.

Since, the building must be perpendicular with respect to surface,

Thus,

(The length of the ladder)² = (The  base of the ladder from the building)² + ( The height reached by ladder on the building)²

Given,

The length of the ladder = 34 ft,

The  base of the ladder from the building = 16 ft.

So,

Hence, the height reached by ladder on the building is 30 ft.

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
