Answer:
decagon is 36° 20-gon is 18°
Step-by-step explanation:
divide de number of sides by 360
N/360
10/360= 36
Long division, use math way
2x-y=32
y-5x=13
transform the second equation to make the elimination possible
2x-y=32
-5x+y=13
now, our ys match, and we can drop them out
2x-y=32
+
<u>-5x+y=13
</u> -3x+0=45
<u>x= -15
</u>
Now we use the meaning of x in one of the original equations
2*(-15)-y=32
-y=32+30
y=-62
The answer is (-15;-62)
