Question

please tell please please please please please​

Answer 1

Answer:

angleOCD=15°

Here angleAOD and angleDOC are linear angles so

angle DOC= 180°-30°=150°

As we know that the diagonals of rectangle bisect each other so

angleODC= angleOCD=X° (let)

In triangle ODC-

angleODC+angleOCD+angle DOC=180°

x+x+150°=180°

2x=30°

x=15°

=> angleOCD=15°

Hope it helps!
