Calculating the measures of interior angles of a triangle
use the diagram showing m || n, as well as the relationships between interior and exterior angles of δabc, to answer the questions.
the measure of angle abc is _ °.
the measure of angle bac is _ °.
the measure of angle acb is _°.

Angle B is the linear pairs with 60°, so the size is 180-60=120°

Angle ABC is the linear pair with 120°, so the size is 180-120-60°

Angle A corresponds to angle 60°, so they are equal

Angle BAC is the linear pair with angle A and angle 70°, so 180-(60+70)=50°

Angle ACB is 180-(50+60) = 70°

The equation of second line in standard form is  

Step-by-step explanation:

Given the second street is parallel to the first street. And the second street is passing through the point .

As the second street is parallel to the first street, the slope of both streets will be the same.

Let us calculate the slope.

We can see that first street is passing through the point and .

So, the slope would be

Now, the slope of second street must be

Let us find equation of second street that is passing through point .

So, the equation of second line in standard form is
