Question

Find the value of y please answer me ​

Answer 1

Answer:

Step-by-step explanation:

we know that the exterior angle of the triangle is equal to the sum of its opposite angles.

so y = ∠BAC+∠BCA

=50°+30°=80°

Answer 2

Step-by-step explanation:

Let triangle angle B in triangle ABC be x

sum of all angles of a triangle is equal to 180°

so, 30°+50°+x=180°

80°+x=180

x=180-80

x=100°

angle x and angle y = B

and B =180°

so, x+y=B

100°+y=180°

y = 180-100

y=80° (answer based on what I learnt in my clases)

HOPE IT HELPS YOU
