Question

Draw a figure of linear pair angles and indicate one angle is 30⁰ and find other angles.​

Answer 1

Answer:

Let <cob=30 degree

<coa and <cob are angles in linear pair

Therefore,

<coa+<cob=180 degree

= <coa+30=180

Therefore, <coa=180-30

= <coa=150

Therefore, <coa will be 150 degree.

Hope this helps.
