Question

find the value of x and y​

Answer 1

Answer:

Step-by-step explanation:

Given = LDCA = 120

TO FIND = X AND Y

PROFF = LDCA+LBCA = 180 ( ANGLES ON A LINE )

               THEREFORE , LBCA = 60

                                    AND LA +LB = 120 (EXTERIOR ANGLE PROPERTY )  ..(1) NOW LA + LB + LC = 180 (ANGLE SUM PROPERTY  OF  A TRIANGLE )

                                      THEREFORE X = Y =  60
