Answer (12,5). In this example, the value "5" is the Y Coordinate.

Step-by-step explanation:

The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate.

Answer:

  y = 24

Step-by-step explanation:

The line marked 'x' is a midline of the triangle, hence half the length of the parallel base line marked '4x-7'. This lets us solve for x and find the lengths of the sides of the triangle.

  2x = 4x -7

  7 = 2x . . . . . add 7-2x

  3.5 = x

Then the horizontal side of the triangle is ...

  4x -7 = 4(3.5) -7 = 7

The hypotenuse of the triangle is ...

  6x +4 = 6(3.5) +4 = 25

The Pythagorean theorem can be used to find y:

  y^2 +7^2 = 25^2

  y^2 = 625 -49 = 576

  y = √576

  y = 24
