Answer:
x=14
y=37
Step-by-step explanation:
9x+12 and 3x are supplementary angles so together they = 180
9x+12 + 3x = 180
12x +12 = 180
12x = 168
x=14
now that uve found x u can find y
4y-10 and 3x are also supplementary angles as well
(plug in x)
4y-10 + 3(14) = 180
4y-10 + 42 = 180
4y = 148
y=37
or another way to find y is to set 4y-10 equal to 9x+12 bc theyre vertical angles, therefore congruent, but it's ur choice
