Question

1) In figure,measures of some angles are given.Using the
measures find the values of x, y, z
​

Answer 1

100 + Y is equal to 180 degree 'linear pair'

Y is equal to 180°-100°

Y is equal to 80°

140 degree + Z is equal to 180 degree 'linear pair'

Z is equal to 180 degree subtracted by 140 degree

the value of Z is equal to 40 degree

Y + Z + x is equal to 180 degree ' angle sum property of a triangle'

80 degree + 40 degree + x is equal to 180 degree

120 degree + x is equal to 180 degree

x is equal to 180 degree subtracted by 120 degree

x is equal to 60 degrees
