Question

Plz help me i dont understand

Answer 1

The value of x = 41

The correct answer is last option

Explanation:

From the figure we can see that,

the line l parallel to line m

To find the value of x

The given two angles are alternate interior angles.Alternate interior angles are equal.

Therefore we can write,

3x - 43 = 80

3x = 80 + 43 = 123

x = 123/3 = 41.

Therefore the value of x = 41

The correct option is last option

Answer 2

`41`

Explanation:

Use the alternate interior angle property to write the equation;

`(3x-43)\degree=80\degree`

Reason: Alternate interior angles are congruent.

Solve the equation for
`x`.

`\Rightarrow 3x=80\degree+43\degree`

`\Rightarrow 3x=123\degree`

Divide both sides by 3.

`\Rightarrow x=(123)/(3)`

`\Rightarrow x=41`
