Question

If two angles of a triangles are 50 degree and 60 degree, then the third angle is?
​

Answer 1

Given,

The two angles of the triangle are 50 and 60 degrees.

To find,

The third angle of the triangle.

Solution,

According to the Angle sum property of the triangle sum of the three angles of the triangle is always 180 degrees.

∠ A + ∠ B + ∠ C = 180°

50° + 60° +  ∠C  = 180°

110° +  ∠C  = 180°

 ∠C   = 180° - 110°

 ∠C   = 70°

Hence, the third angle of the triangle is 70°.
