Answer:
69
Step-by-step explanation:
The sum of exterior angles is 360°, so ...
n° +131° +160° = 360°
n° = 360° -291° = 69°
n = 69

Answer: The picture is black lol
Step-by-step explanation:
Step-by-step explanation:
Given line is 6x+3y=15
Slope of the given line (m)=-x/y
=-6/3
=-2
let slope of the line perpendicular to the given line be m'.
Condition of perpendicularity,
m×m'=-1
-2×m'=-1
m'=-1/-2
m'=1/2
X is equal to 30 (vertically opposite angles)
y=180-50
=130 degrees (angles in a straight line equal to 180)
z=180-130-30 (angle sum of a triangle equal to 180)
z=20 degrees
