Question

Find the value of x and y
give me the answer fast ​

Answer 1

x = 70° [vertically opposite angles]

By angle sum property

y + x + 30° = 180°

y + 70° + 30° = 180°

y + 100° = 180°

y = 180° - 100°

y = 80°

Answer 2

Answer :

• x = 70°

• y = 80°

Step by step explanation :

⇒ x = 70°

• (due to vertically opposite angles)

➥ 30 + 70 + y = (sum of interior angle of triangle)

➥ 30 + 70 + y = 180°

➥ 100 + y = 180°

➥ y = 180 - 100

➥ y = 80°

Lets verify :

★ 30 + y = 180 - 70

★ 30 + 80 = 110°

★ 110° = 110°

★ LHS = RHS

hence proven !!!
