Question

In the given figure ​

Answer 1

Answer:

a) 135°

b) 45°

Step-by-step explanation:

Angle AOB is a straight angle, e.i. it measures 180°. Now, as you can see, angle AOC has been drawn in such a way that it has a ray common with AOB, which is AO. AOB is 180° and AOC is 45° so we will subtract the two, the answer will be 180-45=135°. Now, if you measure is with a protractor, you will see that BOD has the same length as AOC, that is, 45°. So, the answer is 135° and 45° respectively.

I hope my answer helps you. Have a good day.
