    m∠N = 42°

    Step-by-step explanation:

    △CDE∼△LMN




    Given:

    m∠E=7x-14 and m∠N=3x+18

    So

    7x - 14 = 3x + 18

    4x = 32

    x = 8

    Step-by-step explanation:

    6x+2x=8x

    -20+36=16

    Put both answers for both equations into an equation

    8x+16

    now multiply 14 instead of having x

    8 (14) + 16=128
