Question

how can i find the angle measures of trapezoid ABCD inscribed in a circle, only trying to find m 12 years ago

Answer 1

Hint: in a cyclic quadrilateral opposite angles add up to 180 degrees

Answer 2

so if m <a = 60 what is m < C?

Answer 3

i am not sure but i know that m<D is 60 as well

Answer 4

and since AD and BC are parallel then < A and <B add up to 180 also

Answer 5

so then i need to subtract 180-60, right?

Answer 6

yes

Answer 7

i get 120

Answer 8

thats correct <C = 120
also <B = 180 - 60 = 120
