Answer:
x = 40
y = 70
Step-by-step explanation:
The two base angles of the isosceles triangle are congruent. y° and the external angle 110° form a linear pair.
y° = 180° -110° = 70°
y = 70
__
The external angle 110° is equal to the sum of the remote interior angles x° and y°.
110 = x + y
x = 110 -y = 110 -70
x = 40
