Step-by-step explanation: I found this by taking 75 + 15 which is 90 then dividing it by 3 so 30. This is correct because since the linear pair is equal to 75 degrees then this also needs to be 75 degrees and 3 x 30 = 90 and 90 - 15 = 75.
While I have a suspicion you asked your question incorrectly, and the following isnt what you intended to recieve. The answer to this would be 0.0130902291.
