    We are given : m∠WYX = (2x-1) ° and m∠WYZ = (4x+1) °.

    ∠WYX and ∠WYZ are complementary.

    We know, sum of complementary angles is = 90°.

    So, we need to add ∠WYX and ∠WYZ and set it equal to 90°.

    m∠WYX + m∠WYZ = 90°.

    Plugging values of ∠WYX and ∠WYZ in the above equation, we get

    (2x-1) ° + (4x+1) ° = 90°.

    Removing parentheses from both sides,

    2x-1 + 4x+1 = 90.

    Combining like terms,

    2x+4x = 6x and - 1+1 = 0

    6x + 0 = 90.

    6x=90.

    Dividing both sides by 6.

    6x/6 = 90/6

    x = 15.

    Plugging value of x=15.

    m∠WYX = (2x-1) ° = 2*15 - 1 = 30 - 1 = 29

    m∠WYZ = (4x+1) ° = 4*15 + 1 = 60+1 = 61.

    Therefore, ∠WYX=29° and ∠WYZ=61°.
