that is b
Answer:
A
Step-by-step explanation:
As the equation has already been factorised, we can find the value of x that results in 0 in each bracket:
x - 3 >= 0
x >= 3
x+2 >= 0
x >= -2
Answer:
125°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 8 (octagon), thus
sum = 180° × 6 = 1080°
let x represent one of the equal angles, then
3x + 705 = 1080 ( subtract 705 from both sides )
3x = 375 ( divide both sides by 3 )
x = 125
Thus the size of one equal angle = 125°
