    Step-by-step explanation:

    Given that angles in the quadrilateral are

    x° (x-10°) (x+30°) and 2x°

    So, x+ x-10+ x+30+2x=360°

    5x + 20= 360

    5x = 360-20

    5x = 340

    x = 340/5

    x = 68°

    First angle = 68°.

    Second angle = x-10 = 68-10 = 58°.

    Third angle = x+ 30 = 68+30 = 98°.

    Fourth angle = 2x = 2× 68 = 136°.

    Step-by-step explanation:

    We know that sum of all angle of a quadrilateral is 360⁰

    x+x-10+x+30+2x=360⁰

    5x+20=360⁰

    5x=340⁰

    x=340/5=68⁰

    x=68⁰

    x-10= 68-10 =58⁰

    x+30=68+30 98⁰

    2x= 2×68 = 136⁰
