Freezing point of water = 0°C
By adding salt, freezing point lowers by 7°C ;
The freezing point of salt water can be expressed as ;
Since temperature lowers :
Freezing point of salt water :
Freezing point of water - 7°C
0°C - 7°C
= - 7°C
<span>For any angle between 0° and 180°, the supplement of <em>the angle</em> is 180° – <em>the angle.</em></span>
<span><em>=> </em>180-179=1</span>
<span>So the supplement of 179 is 1.</span>
