Answer:
The answer is option 2, by simplifying 9 to 3² to make both powers base 3 and subtracting the exponents.
Step-by-step explanation:
You have to make the expressions into the same base :
Next, you have to apply Indices Law :
EACH central angle = 360 / number of sides
number of sides = 360 / each central angle
number of sides = 360 / 40
number of sides = 9
The two angles are corresponding angles, which means they are equal to each other. Make them equal to each other in an equation.
11x - 2 = 130
Add 2 to both sides.
11x = 132
Divide both sides by 11.
x = 12
