If someone can please answer the question in the picture thatd be great

≈ 20.8 ft

Step-by-step explanation:

A right triangle is formed between the wall, the ground and the ladder.

The ladder is the hypotenuse , the wall and ground are the legs.

let h be the height of the wall, then using Pythagoras' identity

h² + 33² = 39²

h² + 1089 = 1521 ( subtract 1089 from both sides )

h² = 432 ( take the square root of both sides )

h = ≈ 20.8 ft ( to the nearest tenth )

i think the answer is b.

step-by-step explanation:

not 100% sure though.
