Answer 1

Answer:

40 degrees

Step-by-step explanation:

the sum of the interior angle of a traingle is alaways 180 degrees

180--(60+80)

180--(140)

=40°

Answer 2

Answer:

ans:40 degree

Step-by-step explanation:

total of angles =180

from eqs : sum of angles of a n sided polygon

= (n-2) 180

num of sides for triangle 3

so, =(3-2)× 180

=180

so req angle = 180-(80+60)

=40.
