Please mark me as the brainliest

Step-by-step explanation:

In triangle ABC,

70° + x° = 145° [ sum of two angles in a triangle is equal to the opposite exterior angle ]

x° = 145° - 70°

x° = 75°

In triangle ABC,

70° + 75° + y° = 180° [ sum of all angles in a triangle is 180° ]

145° + y° = 180°

y° = 180° - 145°

y° = 35°

x° = 75° and y° = 35°
