Question

If the measures of two angles of a triangle are 97 and 34​, what is the measure of the third​ angle?

Answer 1

Step-by-step explanation:

sim of angles of a triangle = 180

97+34+x =180

131+x = 180

x = 180 -131

x = 149

Answer 2

Step-by-step explanation:

We know that the sum of all angles of a Δ is 180°

1st angle = 97°

2nd angle = 34°

3rd angle = x (we don't know the 3rd angle)

∴ 97° + 34° + x = 180°

⇒ 131° + x = 180°

⇒ x = 180° - 131°

⇒ x = 49°

The 3rd angle is 49°
