Find x (PLS HURRY ITS URGENT) ​
skelet666 [1.2K]

Answer:

<h2>         x = 85° </h2>

Step-by-step explanation:

m∠ADC = 180° - 95°             {a straight angle}

m∠ABC =  180° - x             {a straight angle}

m∠ADC + m∠ABC = 180°     {a quadrilateral inscribed in a circle}

180 - 95° + 180 - x = 180°

     85° - x = 0

        <u>x = 85° </u>
