Question

two angles of a triangle are 30° and 80°. find the thrid angle​

Answer 1

70°

Step-by-step explanation:

Sum of angles of triangle = 180°

30°+80°+ third angle= 180°

third angle= 70°

Answer 2

Answer:

sum if all the angles in a triangle is equal to 180 degrees

1st angle 30 degrees

2nd angle 80 degrees

3rd angle = ?

3red angle = 30+80+x=180

110+x=180

x=180-110

therefore,

x=70degrees
