Answer:
x = 48°
y = 84°
Step-by-step explanation:
solution:
sum of all angles inside the triangle is equal to 180°
x + y + 48° = 180°
interior angle y and exterior angle 96° are supplementary or they add up to 180°,
y + 96° = 180°
y = 180° - 96°
y = 84°
now we know 2 angles, we can find the last one, angle x
x + y + 48° = 180°
x + 84° + 48° = 180°
x + 132° = 180°
x = 180° - 132°
x = 48°
