Angle CBA = 60°
Angle BAC = 40°
Angle BCA =
The measure of angle .
We know that,
➪ ∠ CBA + ∠ BAC + ∠ BCA = 180°
➪ 60° + 40° + = 180°
➪ 100° + = 180°
➪ = 180° - 100°
➪ = 80°
Therefore, the measure of angle is 80°.
Now, the three angles of the triangle are 60°, 40° and 80° respectively.
∠ CBA + ∠ BAC + ∠ BCA = 180°
✒ 60° + 40° + 80° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.
