Answer:
x = 59° , y = 44°
Step-by-step explanation:
See the attached image below ,
Since the whole angle is 180° we can write it like this ,
(2x + 18)° + (x - 15)° = 180°
2x + x + 18 - 15 = 180
3x +3 = 180
3x = 177
x = 177/3
x = 59°
and now for y,
y = (x - 15)° CORRESPONDING ANGLES PROPERTY
y = x - 15
y = 59 - 15
y = 44°
