Question

In each of the following figures, one side of a triangle has been produced. Find all the angles of the triangle in each case. (Please tell the circled part) ​

Answer 1

Answer:

iv) y=40

z=50

x=90

v) y=55

x=70

vi)x=65

Answer 2

130+z=180(linear pair angles)

z=180-130

z=50

140+y=180(linear pair angles)

y= 180-140

y=40

x+y+z=360(angle sum property)

50+40+z=360

90+z=360

z=360-90

z=170
