    Step-by-step explanation:

    Triangles are similar if they have the same shape, but not necessarily the same size.

    in this case we have

    JK/MO = KL/ON = JL/MN

    A) Use properties of similar triangles.

    The measurement of angle J can be derived from triangle MNO.

    Corresponding angle are congruent.

    Angle J in triangle JKL correspond with angle M in triangle MNO.

    Therefore:

    Tangent M = opp/adj

    tanM = 2/1.5

    tanM = 1.3

    M = tan-¹ 1.3

    M = 52.43

    J = M = 52.43°

    B) MO in △MNO corresponds to JK in △JKL

    C) JK/MO = KL/ON = JL/MN

    find JL using Pythagoras theorem

    JL² = KL² + JK²

    JL² = 4²+3²

    JL = √ (16+8)

    JL = 5

    JK/MO = KL/ON = JL/MN

    = 3/1.5 = 4/2 = 5/2.5 = 2/1

    Therefore the ratio of larger triangle to small triangle is 2:1
