Answer:
5
Step-by-step explanation:
6x + 4 + 73 + 73 = 180
6x + 150 = 180
6x = 30
x = 5
Those little marks on AB and BC denote congruence. That makes the triangle isoceles. That means the base angles are equal. Both 73.
Triangle Sum Theory states all angles of a triangle add to 180.
12x+10
9x+3x=12x
and
4+6=10
the absolute value is 3,-13
9√3- ^5√9
you would need to write in exponential form
I believe it's B or C.
