“y” is a part of a straight angle, so
131 + y = 180
y = 180 - 131
y = 49 [degrees].

Here is the ans hope it helps:)
Answer:
x = 5. y = 4
Step-by-step explanation:
7x - 4 = 31

y = 4
Answer:
To find the sum of interior angles in a polygon, we can use the formula:
where n is the number of sides.
Since this is pentagon (5 sides), then 
The missing angle would then be

Since angles on a straight line add up to 180, then
