    Answer:(10,-4)

    12 units

    108 square units

    Step-by-step explanation:

  • keshavgandhi04:

    The coordinate of R is (10,-4), the height of the triangle is 12 units, and the area of the triangle is 108 square units and this can be determined by using the given data.

    Given :

    • The coordinates of the vertices of the triangle are (–8, 8), (–8, –4).
    • Consider QR the base of the triangle.
    • The measure of the base is b = 18 units.

    Given that the coordinates of vertices P(-8,8) and Q(-8,4). If the triangle is a right angle triangle then the coordinates of R is given by:

    R(-8 + 18, -4 + 0) = R(10,-4)

    So, the coordinate of the third vertice is (10,-4).

    The height of the triangle PQR is given by:

    h = 4 + 8

    h = 12 units

    Now, the area of the triangle PQR is:

    [tex]\rm Area = \dfrac{1}{2}\times 18 \times 12[/tex]

            [tex]= 9\times 12[/tex]

            = 108 square units.
