Answer: B) 6

Step-by-step explanation:

"The Corresponding Angles Theorem states: If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent"

So, in this case both expressions are equal (have the same angle measurement) so we can solve for x

(12x+3)=(11x+9)

=12x-11x=9-3

x=9-3

x=6

How to find side length given angle and 2 sides non right triangle?

I assume you mean, that an angle and two sides are known.

A formula that can be used for irregular triangles is the cosine rule.
$a = {b}^{2} + {c}^{2} - 2ab \cos(angle \: opposite \: a)$
'b' and 'c' must be sides that are beside the angle 'A' (angle opposite 'a').

What is the solution of the system? Use substitution.

nekit [7.7K]

Substituting y=6x+2 into equation 3y - 18x =12 looks like:

3(6x + 2) - 18x = 12
18x + 6 - 18x = 12 distributive property left side
6 = 12 simplifying the left side

We now see a contradiction: 6 does not equal 12 What this tells us is that there is no solutions to this equation. So choice 'C' ...
