    Answer:

    PQR = 180° – 130°  

    PR = 150°


    The size of the a PQR

    Given :

    PQ are 2 sides of a regular

    By formula , a × n = 360°

    so, between P and Q angle is 90°

    Then , QR is 12 sided polygon ,so

    a = ?

    n = 12

    a × n = a × 12 = 360°

    a = 360 / 12we

    a = 30°

    Therefore , angle between Q and R is 30°

    The diagonal PR form a triangle

    like,PQR

    we Know that ,

    angle between PQ and QR are 90° and 30°

    angle between ( PQ + QR + PR ) = 180°

    BY , PUT THE VALUE OF PQ and QR

    90° + 30° + PR = 180°

    PR = 180° 120°

    PR = 60°

    The size of the a PQR
