How might people's perception of you affect you in a society?

ExplanatAs we have discussed so far in this chapter, many things impact our human relations with others. Perception is no different. Perception is the recognition and interpretation of sensory stimuli based upon our memory. In other words, it is the way you interpret data around you. The data could come from sight, smell, touch, taste, and hearing. For example, if you wake up in the morning to the smell of coffee, your perception is likely correct that your roommate is already awake. The challenge with perception in human relations is that we may not always understand someone else’s perception and/or assume their perception is our own. This is where disagreements and other communication issues can occur. For example, if you perceive that your significant other is too focused on spending time with friends, your interactions with her will be based upon this perception. For example, you could be frustrated and short tempered. In a workplace setting, perceptions can also cause miscommunications. For example, you may perceive your coworker to be lazy because he always arrives to work at 8:15 a.m. and the start time is 8 a.m. Suppose he has a child with a medical condition who needs special schooling, and the school doesn’t open until 8 a.m.? Perhaps he has made arrangements with your supervisor of which you are unaware. This perception can be a dangerous one, since we don’t have all of the facts.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
