Question

find the value of x and y​

Answer 1

Answer:

(i) x = 50° and y = 80°

(ii) x = 110° and y = 70°

Step-by-step explanation:

(i) y = 80° (Vertical opposite angles are equal)

x + y + 50° = 180° (sum of all angles of a triangle is 180°)

x + 80° + 50° = 180°

x = 180° - 130°

x = 50°

(ii) x = 50° + 60° (sum of two opposite interior angles is equal to the exterior angle)

x = 110°

y + 50° + 60° = 180° (sum of all angles of a triangle is 180°)

y = 180° - 110°

y = 70°
