Question

Please solve this equation. ​

Answer 1

Answers ;

• y = 80
• x = 50

`\sf\longmapsto \: y = 80 \: ( \: since \: its \: vertically \: opposite \: )`

`\sf\longmapsto 50 + x + 80 = 180`

`\sf\longmapsto \: x = 130 - 180`

`\sf\longmapsto \: x = 50`

Answer 2

y = 80°

x = 50°

Explanation:

As the vertically opposite angles are equal,

y = 80°

Also, as the interior angles in a triangle are added up to 180°,

y° + x° + 50° = 180°

80° + x° + 50° = 180°

130° + x° = 180°

x° = 180° - 130°

x° = 50°
