  • Answer:

    Angle C is equal to 30.

    Step-by-step explanation:

    To find angle C, we have to find all the other angles first. They tells us the B ~= BAD ~= ADC. So, if we find ADC, we've found B and BAD as well. ADC is just 180 - 70 (the angle of ADE), which is 110. So, ADC, BAD, and B are equal to 110.

    Remember, angles in a quadrilateral add up to 360. So, add all of the values of angles be have now and subtract from 360:

    360 - (110 + 110 + 110)

    360 - 330 = 30

    Angle C should be equal to 30.

    Hope this helped!
