An exterior angle is 127°.

To find: value of"X"

x+127° = 180°. [Being linear pair]

or, X = 180° - 127°

or, X = 53°

Therefore, the value of "X" is 53°.

Guests at a pizza party are seated at three tables. The small table has 5 seats and 2 pizzas. The medium table has 7 seats and 3

bagirrra123 [75]

Answer:

the 5 seated table with the 2 pizzas got more each.

Step-by-step explanation:

$\frac{5}{2} = 2\frac{1}{y2}$ pieces each

$\frac{7}{3} = 2\frac{1}{3}$ pieces each

$\frac{12}{5} = 2\frac{2}{5}$ pieces each

Now change the fractions s that they all have a common denominator.

$2\frac{1}{2} = 2\frac{15}{30}$

$2\frac{1}{3} = 2\frac{10}{30}$

$2\frac{2}{5} = 2\frac{15}{30}$

Thus meaning that the 5 seated table with the 2 pizzas got more each.
