Answer:

B) 70°

Step-by-step explanation:

The triangle with x is an isosceles triangle, with base angles = 40

40 is the the angle of the triangle with angle y too (vertically opposite angles)

180 - 40 = 140 is the sum of the two base angles

y = 140/2 = 70

Answer:

70

Step-by-step explanation:

The angle not marked in the top triangle is 40 degrees since it is an isosceles triangle.  That makes the angle opposite it in the other triangle 40 degrees since they are vertical angles and vertical angles are equal.

The bottom triangle has 3 angles that sum to 180 degrees,  The other angle not marked is also y since it is an isosceles triangle.

40 + y +y = 180

Subtract 40 from each side and combine like terms

40-40 +2y = 180-40

2y = 140

Divide by 2

2y/2 = 140/2

y = 70
