Find the values of angles x, y, and z.
A large triangle is divided into two smaller triangles by a line segment that extends from the upper vertex to the side opposite.• In the triangle to the left, the segment that divides the larger triangle into two smaller triangles forms a 40 degree angle with the side at the bottom of the triangle. The angle to the left in this smaller triangle is labeled x and the angle at the top of this triangle measures 60 degrees.
• In the triangle to the right, the line segment that divided the larger triangle into two smaller triangles forms an angle that is labeled y with the side at the bottom of the triangle. The angle to the right in this triangle measures 20 degrees and the angle at the top of this smaller triangle on the right is labeled z.
A. x = 80°; y = 140°; z = 20°
B. x = 70°; y = 130°; z = 30°
C. x = 80°; y = 50°; z = 110°
D. x = 100°; y = 140°; z = 40°
