Question

an exterior angle of a triangle is 130 degree and one of the interior opposite angle is 45° find other two angle of a triangle

Answer 1

i think i give that ans

Answer 2

we know from theorm that exterior angle is equals to sum of the two opposite interior angles
so let another interior angle be X, then X+45=130
X=130-45=85degree
now if two angles of a traingle are 85 and 45 then third angle will be
180-(85+45)=180-130=50 degree
hence,your answers are 85 and 50 degree
