Question

HELP, Would I have to subtract 180 from 70 to get the answer for C?? What would the answer be?

Answer 1

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!
