Answer:
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°.
2x+3=17
subtract 3 from each side
2x+3 -3 = 17 -3
2x = 14
divide by 2 on each side
2x/2 = 14/2
x = 7
Answer:
Step-by-step explanation:
2(4 + x) = 34
4 + x = 34/2 = 17
x = 17 - 4 = 13
