1. Check the drawing of the rhombus ABCD in the picture attached.
2. m(CDA)=60°, and AC and BD be the diagonals and let their intersection point be O.
3. The diagonals:
i) bisect the angles so m(ODC)=60°/2=30°
ii) are perpendicular to each other, so m(DOC)=90°
4. In a right triangle, the length of the side opposite to the 30° angle is half of the hypothenuse, so OC=3 in.
5. By the pythagorean theorem,

6. The 4 triangles formed by the diagonal are congruent, so the area of the rhombus ABCD = 4 Area (triangle DOC)=4*

Answer:
1: c
2: face
Step-by-step explanation:
pretty sure
For finding the measure of C you should know a line is 180° so 124°+C = 180
now you can say:
C = 180°- 124° = 56 °
so the answer is 56° :)))
i hope this is helpful
have a nice day
