Question

Please help I need to find X

Answer 1

x = 12

Explanation:

if l and m are parallel that means that since the two angles are consecutive interior they add to 180

so add them both and set that to 180

9x - 4 + 5x + 16 = 180

now combine like terms

14x + 12 = 180

subtract 12 from both sides

14x = 168

divide everything by 14

x = 12

that is the answer

Answer 2

• 
  `\sf x=12^o`

Explanation:

Let's find x:-

`\sf 9x-4+5x+16=180^o`

Combine like terms:-

`\sf 9x+5x-4+16=180`

`\sf 14x-4+16=180`

`\sf 14x+12=180`

Add/Subtract numbers:-

`\sf 14x+12-12=180-12`

`\sf 14x=168`

Divide both sides by 14:-

`\sf \cfrac{14x}{14}=\cfrac{168}{14}`

`\sf x=12^o`
