Question

Find the values of the unknowns x and y in the following diagrams:​

Answer 1

Answer:

a) sol. :

y+ 120 = 180(straight angle)

y= 60

again,

x+y+ 50 =180(angle sum property)

x=180-50-60

x=70

b) Sol. :

y=80 ( vertically opposite angles)

now,

x+y+50=180(angle sun property)

x=180-50-80

x=50
