Question

if m angle1=(4x+12), angle2= (7x+3), and m angle 3= 6y then x =? m angle 1=?, and m angle 2 =? and y =?? help!!! plz

Answer 1

from figure we see
angle 4 =180-angle 1
and by vertical angle theorem angle 2 and angle 4 are equal
so 7x+3=180-4x-12
so x=15
and 4x+12=6y ---by vertical angle theorem
so y=12
you can switch these values into angle 1 angl2 and get your answer

Answer 2

angle 1=72
angle 2=108

Answer 3

thank you!
