The third angle of the triangle will be ∠B = 69°.
What is an angle?
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that:-
- Two angles are ∠A = 43° and ∠C=68°
The third angle will be calculated as:-
∠A + ∠C + ∠B = 180
43 + 68 + ∠B = 180
∠B = 180 - 43 - 68
∠B = 69°
Therefore the third angle of the triangle will be ∠B = 69°.
