Answer:
14
Step-by-step explanation:
Triangle is a 45 45 90 right triangle
Ratio of leg : hypotenuse = x : x√2
Given leg = 7√2
so hypotenuse x = 7√2 * √2 = 14
The inverse of the equation y = x² - 4, x≤ 0 is 
<h3>How to determine the inverse of the equation?</h3>
The equation is given as:
y = x² - 4, x≤ 0
Swap the x and y values
x = y² - 4
Add 4 to both sides
y² = x + 4
Take the square root of both sides

Hence, the inverse of the equation y = x² - 4, x≤ 0 is
