Question

5. If m∠ADC = 105°, then m∠ABC =
6. If m∠DAB = 70°, then m∠ABC =

Answer 1

5. ABC = 105 degrees

6. ABC = 110 degrees

Explanation:

5. Opposite angles of a rhombus have equal measure.

6. The four interior angles of a rhombus equal 360. If DAB = 70, then DCB = 70, and ADC + ABC = 120, and are equal, so each equals 110.
