Hello
(n-2)*180 where n is the number if angles in a polygon
(38-2)*180
=36*180=6480
(29-2)*180=4860
1 angle -> 4860/29 = 167.58
You do the same here
(1026-2)*180=184,320
184,320/1026=179.64
They're complementary so 180-179.64=0.36°
(36-2)*180=6120
6120/36=174.85
180-175.85=5.15°
Answer:
10x^2 +2x -9
Step-by-step explanation:
Group things that are alike and simplify
(3x^2+7x^2) = 10x^2
(2x) nothing to add or subtract with it so it stays positive 2x= +2x
(-5-4) = -9
Then put the answer from highest degree to lowest
This is the definition of the midpoint of a line segment.
The midpoint is, by definition, the point on the line segment that splits it in two equal (congruent) segments.
