Atriangle has angle measurements of 77°, 27°, and 76°. what kind of triangle is it?

That is so true, i can’t believe how true this is

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)
