I believe the answer should b the second option :)
A variable represents an unknown number
Answer:
x = 6
Step-by-step explanation:
opposite sides of both angles are congruent/equal or have same measure.
Therefore:-
6x+2=38
6x=38-2
6x=36
x = 6
(10x + 4) + (5x-4) ≈ 180
solve for x and you get x≈12
plug 12 in to 5x-4 and you get 56
