In a regular octagon all the interior angles are of the same value.
sum of the interior angles in octagon = (n-2) *180°
n - number of sides, in this case, n = 8
interior angles sum = (8-2)*180° = 6*180° = 1080°
since there are 8 equal angles = 1080/8 = 135°
Angle x + one interior angle of the octagon = 180 ° (as its a straight line)
x + 135 = 180
x = 45°

Answer:
2x^2+10-3x
Step-by-step explanation:
start by multiplying numberes into the parentheses.
2x^2+10-3x-3+3
now combine like terms
2x^2+10-3x
Answer:
Ok,(-5,__) means that -5 is the x intercept and the missing number is the y intercept
So, We need to substitute x with -5 in the equation to get the value of y
x-5y=-15
-5-5y=-15
-5y=-15+5
-5y=-10
-5y/-5=-10/-5
y=2
So,the missing value is 2. (-5,2)
