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.

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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
