Question

Plz help me i dont understand

Answer 1

Answer:

$m\angle ABC=35\degree$

Step-by-step 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

$m\angle ABC=35\degree$

Answer 2

Answer:

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

Step-by-step 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°
