y= 180-131 = 59

OpenStudy (princeharryyy):
z = 59+65 = 124. check the calculations.

OpenStudy (rz172):
I thought;
x = 65
y= 49
z = 49 + 65

Below MAY be right ...
x=65 (angles of a triangle)
y=49 (angles on a straight line)
angle on the same straight line as z = 82
z=98 (angles on a straight line add up to 180)

How do I find this?

OpenStudy (princeharryyy):
nah! @osprey. that's incorrect. 114 is right.
