4,9, 36, 49, 121, 144, 196, 225
Y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)
x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)
Therefore, m/_x = 48 degrees.
M= a + n
I’m not sure if this is what you were looking for but I hope this helps
First;
-8≤2x-4
-4≤2x
-2≤x
Then;
2x-4<4
2x<8
x<4
-2≤x<4
C is the correct answer.
