Answer:
\sqrt(3)[cos((4\pi )/(45))+isin((4\pi )/(45))]
Step-by-step explanation:
The first one.
Y=mx+b is Slope Intercept Form, where m represents the slope and b represents the y-intercept.
The y-intercept is the value of y when x equals 0, and can be visualized on a graph as the point on the line when it crosses the y-axis.
Ok, so you have your equation, 5·x+5-(5x+25).
First, do the prathases, so you have, 5x+5-5x-25.(5·x also means 5x)
Now, you need to combine like terms, and through that the xs cancel out, so you are left with -20 as you answer.
The order of the sides of the triangle is bc>ab>ac as per the rule that side opposite to the larger angle is larger
