Answer:
the measure of <UXW is 57°
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°
Step:6x+12y-6z+7x+7y-28z
Answer:13x+19y-34z
3rd answer always solve parenthesis first use PEMDAS
-4x + 6y = 24
4x + y = -10
7y = 14
y = 2
2x - 6 = -12
2x = -6
x= -3
