  1. Answer:

    The other angles are [tex]30^\circ[/tex] and [tex]45^\circ[/tex]

    Step-by-step explanation:

    Let the missing angle be represented as x

    Then the two angles of ration 2:3, can be represented as 2x and 3x.

    Using the triangle-angle-sum theorem:

    [tex]2x+3x+105^\circ=180^\circ\\5x+105^\circ=180^\circ\\5x=180^\circ-105^\circ\\x=15^\circ[/tex]

    Then the other angles are:

    [tex]2x=2(15)=30^\circ\\3x=3(15)=45^\circ[/tex]

  2. Answer:

    30 and 45

    Step-by-step explanation:

    Sum of all angles of triangle is 180 degree so

    2x + 3x + 105 = 180 this gives

    5x = 75 this gives

    X= 15

    So 2x= 2(15) =30 degree

    And 3x = 3(15) = 45 degree
