The sum of the measures of three adjacent angles is 150∘. The measures of the angles are in the ratio of 1:2:3. What is the measure, in degrees, of the largest angle?

hope it is correct if not i'm srry i tried to

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
