There isn't any. Dilations do not affect angles.
The addition of an extra side increases the total of the internal angles by 180° The sum of the internal angles of a polygon = (number of sides - 2) × 180°
Nothing. Translation does not affect the measure of sides (or angles).
If all side lengths are changed so the new shape is proportionately equal, the angles don't change. But if it's not proportion. equal, then the angles will be different
To determine the tension in each chain, we first need to calculate the angles the chains make with the vertical. Using trigonometry, we find that the angles are approximately 53.13 degrees and 37.76 degrees for the 4m and 3m chains, respectively. Next, we can use the equilibrium condition to set up equations for the forces in the vertical direction. By solving these equations simultaneously, we can find the tensions in the two chains to be approximately 707.11N and 565.68N.
