<span>The sum of the interior angles of any regular polygon is (n - 2) X 180
30 = n
</span><span>[(30) - 2] × 180
</span>28 X 180
5040
<span>The interior angle of a regular polygon = the sum of interior angles ÷ number of sides</span>
5040 <span>÷ 30 = 168</span>
Therefore the measure of each interior angle in a regular 30-sided polygon is 168°
Answer:
whats the question bro
Step-by-step explanation:
2x - 2y + z = 5....multiply by -1
2x - 2y + 3z = 7
-------------------
-2x + 2y - z = -5 (result of multiplying by -1)
2x - 2y + 3z = 7
-------------------add
2z = 2
z = 2/2 = 1
2x - 2y + z = 5.....multiply by 3
-3x - 3y + 3z = 9...multiply by 2
-------------------
6x - 6y + 3z = 15 (result of multiplying by 3)
-6x - 6y + 6z = 18 (result of multiplying by 2)
-------------------add
-12y + 9z = 33
-12y + 9(1) = 33
-12y + 9 = 33
-12y = 33 - 9
-12y = 24
y = -24/12
y = -2
2x - 2y + z = 5
2x - 2(-2) + 1 = 5
2x + 4 + 1 = 5
2x + 5 = 5
2x = 5 - 5
2x = 0
x = 0
solution is : (0,-2,1)
Answer:
83
Step-by-step explanation:
tax plus tip is 35%
35% of 100 is 35
48 + 35 = 83
Your answer would be f^-1 (x)= 2x/3
