---> 0 <---
suppose this "0" is an arbitary object. The net force will be against it from both sides (left and right)
<h3>Solution:</h3>
<u>Given:</u>
<u>In the diagram given, we can tell that:</u>
- ∠A and ∠B are a linear pair.
- ∠B and ∠C are a linear pair.
<u>This means that:</u>
- ∠A + ∠B = 180°
- ∠B + ∠C = 180°
<u>Step-1: Find ∠B.</u>
- ∠A + ∠B = 180°
- => 50 + ∠B = 180°
- => ∠B = 180 - 50
- => ∠B = 130°
<u>Step-2: Find ∠C.</u>
- ∠A = ∠C (Vertically opposite angles
- => ∠C = 50°
