The measure of one interior angle of a triangle is 40 degrees. The second interior angle is ten degrees less than twice the measurement of the third angle. What are the other two interior angles?

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)
