Geometry please help i’m trying to go to college

hahaha

ok so 70=z

a line is 180 degrees

so 180-70 is 110

so set the 4x+12 = 110

solve for x

u figure that out i don' t feel like doing that rn

once you find x

input it into 3x

get an answer

then add z (z is 70, from the beginning) to the answer u just got

and then ur gonna take that answer and subtract it from 180 degrees(3 angles of a triaNile add to 180 degrees)

then u should get you answer

have a nice day and stay safe

hope this helps

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
