Step-by-step explanation:
To find the sum of the measures of the intereor angles of each convex polygon
we using formula
<h3>#4</h3>
we can put the value of x is 54
then,
<h3>#5</h3>
we can put the value of x is 19
then,
#6
we can put the value of x is 292
then,


- =》 52200°
#7
we can put the value of x is 5
then ,


- =》 540°

</span>right triangle
<span>Proof: You can apply the Pythagorean theorem.</span>
Y = x + 4
y = -x - 6
x + 4 = -x - 6
x + x = -6 - 4
2x = -10
x = -10/2
x = -5
y = x + 4
y = -5 + 4
y = -1
one solution : (-5,-1)
