Question

Plz help finding x. Will give brainliest

Answer 1

Answer:

$x=120^o$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

step 1

Find the measure of angle ABC

we know that

$m\angle ABC=70^o$ ----> by alternate interior angles

step 2

Find the measure of angle x

we know that

The Exterior Angle Theorem states that The exterior angle of a triangle is equal to the sum of the two opposite interior angles

so

In the triangle ABC

$x=m\angle ABC+m\angle ACB$

we have

$m\angle ABC=70^o$

$m\angle ACB=50^o$

substitute

$x=70^o+50^o=120^o$
