19. find the value of x in the given figure: 2x + x + 3 3x-4) 3x - 4 c a) x = 32.3 b) x = 29 c) x = 27.7 d) x = 31

Answer is B 29

The summation of the interior angles of a triangle =180

Therefore... 2x+7+x+3+3x-4=180

Grouping like terms give 6x+10-4 =180

6x+6. =180

6x =180-6

6x. =174

Dividing both sides by 6

Hence x=29

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
