Question

An exterior angle of a triangle is 120 degrees and one of the interior opposite angles is 40 degrees .find the other two angles of a triangle​

Answer 1

Step-by-step explanation:

exterior angle is 120 degree and 1 opposite interior angle is 40 degree

so,

Let The Other interior opposite aangle be x

120°= X+40°

X =120°-40°

X =80°

than the other angle isi

Let The Other angle be y

angle sum property

80°+40°+y= 180°

y= 180°-(80°+40°)

y =60°
