Respuesta :

B= 120° because all triangles equal 180° so 19°+41° = 60 and 180° -60 equals 120°


A= 120 because B and A are vertical angles

Y= 22° because 120 +38= 158 and 180-158 = 22°

Answer:

a = 120

b = 120

y = 22

a and b and vertical angles

Step-by-step explanation:

angles A and B are vertical angles so they're equal.

you can find angle b because all the angles in a triangle add up to 180

19 + 41 + B = 180

b = 180 - 19 - 41

b = 120

and since theyre equal, that means

a = 120 as well.

since you know a = 120 you can find y.

120 + 38 + y = 180

y = 180 - 120 - 38

y = 22
