Question

If one angle of the triangle is 30 degree and another if 40 degree what is the means of third angle Option first 20 degree s 110 degree 3rd 290 degree for 30 degree answer

Answer 1

Answer:

sum of the three angles of a triangle is 180°

one angle is 30°

another angle is 40°

so the 3 rd angle is

{180-(30+40)}°

=(180-70)°

=110°

so 2nd option is the right answer
