Question

if an exterior angle of a triangle is 110 degree and one of its interior opposite angle is 70 degree then the other one is

clearly give the answer​

Answer 1

Answer:

40°

Step-by-step explanation:

the sum of angles of a triangle= 180°

therefore first we will find the interior angle of the exterior one.

therefore 180° - 110° = 70°

Now let the third angle be x

70°+70°+x = 180°

140°+x =180°

x = 180°-140°

X= 40°
