Answer:

y = 14°

Step-by-step explanation:

since we can see it is an isosceles triangle so

base angles of isosceles triangle are equal then

2x = 50°

50° + 2x + 5y + 10° = 180° { being sum of angles of triangle }

50° + 50° + 5y + 10° = 180°

110° + 5y = 180°

5y = 180° - 110°

5y = 70°

y = 14°

Hope it will help :)
