Question

Plzzz solve the 18th one

Answer 1

Answer:

62

Step-by-step explanation:

As the diagonals of the rectangle bisect, each other,

AO = OC = DO = OB

In triangle AOB,

AO = OB,

So the triangle formed is an isosceles triangle

Angle OAB = Angle OBA = 28

In a rectangle, all the angles are 90

Therefore,

Angle OBC + Angle OBA = 90

Angle OBC + 28 = 90

Angle OBC = 62
