In the given figure, AB= DB and AC= DC If angle ABD= 58°, angle DBC = (2x-4)°,angle ACB=y+15° and angleDCB=63°,find the values of x and y

y+15=63 ( given angle DCB is 63)
y=63-15
=48 degrees

Since angle ABC and BCD are adjacent angles their sum is 180
58+2x-4+63=180
117+2x=180
2x=180-117
=63
x =63/2
=31.5 degrees
