Since angle 4x and 8x look like supplementary angles 4x+8x=180°. After solving that equation x=15. Plug that number in and 4x=60° and 8x=120°
B then that’s how you get the answer
B is the answer I gotchu.
explanation: m1=-4 m2=4 so yes that’s perpendicular.
I belive its
-5 × 6( 3 × 2 - 12x + 30 )
-5 × 6( 6 - 12x + 30 )
-5 × 6( -12x + 36 )
-30 ( -12x + 36 )
From this point you distribute (-30)
( 360x + -1,080 )
Then divide 360 from x and -1,080, to get -3 = x or i guess -3x then divide -3 by -3 to get just x by itself
Im not sure hope this helpes
