Question

Please solve 3rd question in the pic.

Answer 1

50 +50 +x = 180( in triangle)
x=80
80 +50= 180(linear pair)
130 not equal to 180 angles are given wrong

Answer 2

yes the exterior angle is wrong because
exterior angle= sum of the interior opposite angles
that means 50+50=100° but in the figure it is given as 50°
