Question

find x and y in the following figure
​

Answer 1

Answer:

in triangle CAB,

angle A+angle B + angle C=180° .....angle sum property of triangle

angle C +56+y-20=180

angle c+56+40=180....fact

angle c+96=180

angle c=180-96=84

in triangle CAB

C+A+B=180

84+56+y-20=180....angle sum property

120+y=180

y=180-120

y=60
