Question

Find the value of x and y in the given figure
​

Answer 1

Answer:

x=60° ( V.O.A )

30° + 60° + y = 180°

90° + y = 180°

y = 180° - 90°

y = 90°

Answer 2

Answer:

$\sf \huge \green {\therefore \: y = 30 \degree}$

$\sf \huge \green {\therefore \: x = 120 \degree}$

Step-by-step explanation:

Exterior angle = Sum of interior opposite angles

60° = 30° + y

y = 60° - 30°

$\sf \green {\therefore \: y = 30 \degree}$

30° + 30° + x = 180° ( By angle sum property )

60° + x = 180°

x = 180° - 60°

$\sf \green {\therefore \: x = 120 \degree }$

In this answer, we learnt:

• Exterior angle = Sum of interior opposite angles

• Angle sum property
