Correct Answer
Option C
Explanation
To solve the problem and justify why Option 3 is correct, we need to analyze the angles in the parallelogram ABCD with diagonal BD. Given: - тИаADB = 60┬░ - тИаCDB = 28┬░ - тИаCBD = 12x - тИаABD = 7y In a parallelogram, opposite angles are equal, and the sum of angles around a point is 360┬░. Since BD is a diagonal, it divides the parallelogram into two triangles,тАжRead More
