Question

The model below is used to show the relationship between the side lengths of a right triangle. which describes the square that could be connected to side b of the triangle to correctly complete the model? please use step by step instructions.

Answer 1

Answer: D. A square with side length of 20 feet.

Step-by-step explanation:

To determine the side length of the square that could be connected to side b of the triangle to correctly complete the model, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Hypotenuse = side length of square C

Adjacent side = side length of square A

Let B represent the side length of the required square.

Area of square = (side length)²

Therefore,

841 = 441 + B²

B² = 841 - 441 = 400

B = √400

B = 20 ft
