Answer:
15
Step-by-step explanation:
what i did since we know a triangle is 180°, I added all the x's so all the x's added up to 12. i did 180÷12 because you want to find what just one x is
w. k. t, sum of interior amgles of a triangle = 180
therfore 6x + 4x + 2x = 180
12x = 180
x = 15
so, 6x = 6(15)
= 90
4x = 4(15)
= 60
2x = 2(15)
= 30
