Answer 1

Answer:

In figure A :

• < B = 110°

Opposite angles of parallelogram are equal

• y = 110°

Sum of alternate angles is 180

• x = 180 - 110
• x = 70°

In figure B :

Diagonals bisect each other

• 2x - 5 = 15
• 2x = 15 + 5
• 2x = 20
• x = 20/2
• x = 10

• y + 7 = 10
• y = 10 - 7
• y = 3
