Answer:
Step-by-step explanation:
The side of the house is a side of the right triangle.
The ladder is 3 feet away, so it forms a triangle with sides 3, 10, x.
We're trying to find the hypotenuse, which is given by Pythagoras' Theorem:
All real numbers would be the domain here
The answer is C. 207 cm. The formula to find the area of a triangle is 1/2 base times height. So the base is 9cm and the height is 7cm. Multiply them and you get 63, but you have to divide by 2 because the formula so you get 31.5 cm. Multiply that by 4 because there are four triangles. So you get 126 cm. Then to find the area of the square, you do s times s. Side times side so 9 times 9 is 81. Add the 81 and 126 together and your answer is 207. hope i helped ya!!
The answer is going to be 8 because it’s all real numbers greater than or equal to 8
