Question

AC and BD are diagonals of a rectangle intersecting each other at O if OAB = 40* then find the DOC angle

please give step by step explanation no spam ​

Answer 1

Answer:

Here, We have ABCD a Rectangle.

We know that,

AB||CD (Sides of Rectangle)

<OAB = 40°

<OCD = 40° ( Alternate Int. Angles)

Now,

<OCD + < DOC = 180° (consecutive angles)

40° + <DOC = 180°

<DOC = 180° - 40°

<DOC = 140°
