Answer:

y=1/2x-2

Step-by-step explanation:

To find the slope find two perfect points or "pretty points" and rise/run it to get the slope.

I used the y-intercept (0,-2) and (2,-1)

To move from the y-intercept to the next point I rose 1 and and went over 2, or 1/2.

You can also use the equation y-y/x-x on the two points to get the slope, but I used the other way.

Suppose an isosceles triangle has two sides of length 42 and 35, and that the angle between these two sides is 120 degree. what

Citrus2011 [14]

Suppose that a=42, b=35, c is unknown, and C = 120°

$c^2 = a^2 + b^2 -2ab(cosC)$

$c^2 = 42^2 + 35^2 -(2*42*35*cos120)

(cos120=-0.5)

c^2 = 1764 + 1225 -(2940*cos120)

c^2 = 2989 -(2940*-0.5)

c^2 = 2989+1470

c^2=4459

c= \sqrt{c^2} 

c=\sqrt{4459}$
