Answer:
Option C is the best choice.
Step-by-step explanation:
✺ First , Let's know about Corresponding angles :
- A pair of interior and exterior angles which lies to the same side of a transversal.
- Remember that the corresponding angles are always equal.
- The easiest way to think of corresponding angles is the 'F - Pattern'.
✎ Now, In our case , x ° and ( 3x - 70 ) ° are corresponding angles. Set up an equation and solve for x.
{ Move 3x to left hand side and change it's sign )
{ Combine like terms }
{ Divide both sides by -2 }
The value of x is 35°
Now, As we are asked to find the value of m ABC , replace the value of x :
Therefore , m ABC = 35°
And we're done !
