Answer:
x=20 degrees
Step-by-step explanation:
complementary means the angles equal 90 degrees
so ∠A+∠B=90 degrees
∠A=3x-2 and ∠B=x+12
so subsitute
(3x-2)+(x+12)=90
then solve for x
4x+10=90
4x=80
x=20 degrees is your answer

Answer:
m<2= 48
m<3= 52
m<4= 48
Step-by-step explanation:
the opposite of 1 is 3 so 3 is 52 bc opposite angles have the same degree
to find angle 4 you subtract 90 by 52 bc 90 is the total for angle 1 and 4
to find angle 2. u find the opposite of it which is 42 and like i said opposite angles have the same degree
hope this helps
