Question

Plz help me i dont understand

Answer 1

the correct answer is third option m<ABC = 35°

Explanation:

From the given figure we can see that, two corresponding angles.

Corresponding angles are equal.

To find the value of x

we can write,

x = (3x - 70)

3x - 70 = x

3x - x = 70

2x = 70

x 70/2 = 35

To find the value of m<ABC

m<ABC = 3x - 70 = 3*35 - 70 = 105 - 70 = 35

Therefore m<ABC = 35°

Answer 2

`m\angle ABC=35\degree`

Explanation:

Corresponding angles are congruent.

Use this property to write the equation;

`(3x-70)\degree=x\degree`

Group similar terms;

`3x-x=70`

Simplify;

`2x=70`

`\Rightarrow x=35`

`m\angle ABC=x\degree`, corresponding angles are equal

`m\angle ABC=35\degree`
