Question

In the adjoining figure, find the size of each lettered angle.
​

Answer 1

Answer:

according to angle sum of triangle = 180

80 + 52 + x = 180

x = 180 - 132

48

x = 48

a a linear pair constitutes a total angle of 180 degree

143 and z = linear pair

z = 180 - 143

37

z= 37

according to angle sum

x + z + y = 180

48 + 37 + y = 180

y = 180-85

95

y = 95
