    Fahrenheit = (Celsius * 9/5) + 32

    Fahrenheit = (10 * 9/5) + 32

    Fahrenheit = 18 + 32

    Fahrenheit = 50

    m<AEC = m<BED

    5x - 20 = x + 50

    5x - x = 50 + 20

    4x = 70

    x = 70 / 4

    x = 17.5

    m<AEC = 5x - 20

    m<AEC = 5(17.5) - 20

    m<AEC = 87.5 - 20

    m<AEC = 67.5

    m<CEB = 180 - m<AEC

    m<CEB = 180 - 67.5

    m<CEB = 112.5

    I hope this helped
