Question

line AB and line CD intersect each other at point o. if measure of angle AOC=145° then find the measure of angles BOC, BOD and AOD​

Answer 1

Answer:

145

Step-by-step explanation:

Vertically opposite angles

mark me as thanks

Answer 2

Answer:

<BOC = 35 deg, <BOD = 145 deg, <AOD = 35 deg

Step-by-step explanation:

The above photo is the diagram for the question

Here AB and CD intersect at O.

<AOC = 145 degrees

As we can see that AB and CD are intersectimg lines, these will have vertically opposite angles.

so <AOC and <BOD are vertically opposite angles, so

<BOD = 145 degrees.

By linear pair <AOD = 180 - 145 = 35 degrees

And <BOC = <AOD since these are vertically opposite angles.

=> <BOC = 35 degrees.

Hope it helps.......

Thank you......❤❤❤
