Question

Solve this problem please

Answer 1

right answer is b). 27°

Answer 2

IN THE FIG

LET THE MID POINT BE O

AB is a straight line

By Linear pair axiom

40° + 35°+ ∠AOD = 180°

75+ ∠AOD = 180°

∠AOD = 180°- 75°

∠AOD = 105°

ALSO,

again by linear pair axiom

∠y +48° + 105° = 180°

∠y = 180 - 153

∠y = 27°
