Using polygon stuvw what is m angle u ?

The m∠ U is 72°.

Step-by-step explanation:

Given:

To find :

Solution:

The sum of the measures of the interior angles of a polygon with 'n' sides is given as

Here we have n = 5 on substituting the values we get

Therefore,

m∠ U is 72°.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
