e big quadrilateral below and record the given information on the diagram. Use I your knowledge of quadriaterals and triangles to find the measures of the missing rite the measures in their proper place on the diagram, being sure that any measrecord on the diagram are comect. Incorrect answers may lead to more incorrect You may not use protractors or rulers. (Hint: Record every measure you know, even an angle you are asked to find. It may help you find a missing measure.)
Given:
Find:
15.
30 .
\( \mathrm{m} \angle A B C=104 \).
\( \mathrm{m} \angle 8 \)
m \( \angle 9 \)
\( \overline{A C} \perp C D \).
\( \mathrm{m} \angle 10 \)
m \( \angle 11 \)
