The formula of the measurement of an exterior angle of a regular polygon is
β = 360°/n
where β = exterior angle and n = number of sides
Therefore,
n = 360°/β = 360°/18° = 20 sides
No nothing is even it is supposed to have 2 pairs of congruent and parallel sides
Answer:
12^3 PLS GIVE ME BRAINLIEST
Step-by-step explanation:
because u multiply 12 3 times so 12^3
( x + 1 )/ 3 = x + 2
Multiply 3 on both sides
x + 1 = 3x + 6
Subtract 6 on both sides
x - 5 = 3x
Subtract x from both sides
-5 = 2x
Divide 2 from both sides
x = -2.5
There are 146 - 84 = 62 girls
ratio is 84:62
simplifies to 42:31
