Answer:
?=9
Step-by-step explanation:
We have a special right triangle, the 45-45-90 triangle.
In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.
Since we know that the side length is 9, this means that:

The ? is 9.
The answer is C. 29.04
You use the Pythagorean theorem for the diagonal side because it’s a right triangle then you add all the sides and get C
The slope is -1/2. When it’s in the equation like that, the slope is always the number that has the letter X next to it.
Answer:
It is a diagnal line that goes through (0,0) and (1,1) and has a slope of 1
