Question

what is the value of y ?

Answer 1

Answer:

98

Step-by-step explanation:

Answer 2

First find the total of the entire straight line. We know that a straight line is 180 degrees.

Since we already have 2 given numbers, add them.

51+31=82

Since we already have 82 degrees, subtract it with 180.

180-82=98.

So, y = 98
