Answer:
x=20°
2.
x=27°
Step-by-step explanation:
sin(x+20)=cos (2x+10)
=sin (90-(2x+10))
so x+20=90-(2x+10)
x+20+2x+10=90
3x=90-30
3x=60
x=60/3=20
2.
2x+14+x-5=90
3x+9=90
3x=90-9=81
x=81/3=27
-21x+28 is factored into:
-7(3x-4)
For this case, what we should know is that a polygon is a geometric figure with n sides that is closed. It is usually the union of straight lines.
On the other hand, in order to find the area of a figure, we need it to be closed.
Therefore, the edges of an area are confined by snap points.
