Answer:
x -2y = -4
Step-by-step explanation:
The slope of the line between points C and D is ...
m = (y2 -y1)/(x2 -x1)
m = (7 -13)/(5 -2) = -6/3 = -2
The slope of the perpendicular line is the opposite reciprocal of this: -1/(-2) = 1/2. The point-slope equation of the desired line is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -1 = 1/2(x -(-2))
We can rearrange this to standard form.
2y -2 = x +2 . . . . . multiply by 2
-4 = x -2y . . . . . . . subtract 2y+2
x -2y = -4 . . . . . . standard form equation of the desired line
1. We have to prove that in a 45°–45°–90° isosceled triangle, the hypotenuse is times the length of each leg.
2. Since, triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, which states
But, in isosceles triangle it becomes
3. By combining like terms, we get
4. Now, we will determine the principal square root of both sides of the equation.
5. Dividing both sides of the equation by '2', we get
So,
6. So the hypothenuse c is times the length of each leg 'a'.
