Hope it will help you MRK ME As BRAINLIEST

Step-by-step explanation:

<BAD = 90° ( ABCD is a rectangle)

<CAD = <BAD-28

= 90 - 28

= 62°

<CAD = 62°

Now,

In Triangle CAD and DBC

<ADC = <BCD (each 90°)

AD = BC (Opposite sides of rectangle)

CD =DC (common)

So, Triangle CAD congurent Triangle DBC

<DBC = <CAD (C. P. C. T)

< DBC = 62°

<OBC = 62°
