Find the values of angles h, f, and g.
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 130 degree angle with the side at the bottom of the triangle. The angle to the left in this smaller triangle measures 20 degrees and the angle at the top of this triangle is labeled lower h.
• In the triangle to the right, the line segment that divided the larger triangle into two smaller triangles forms an angle that is labeled lower g with the side at the bottom of the triangle. The angle to the right in this triangle is labeled lower f and the angle at the top of this smaller triangle on the right is labeled 60 degrees.
A. h = 40°; f = 20°; g = 50°
B. h = 30°; f = 60°; g = 50°
C. h = 30°; f = 70°; g = 50°
D. h = 60°; f = 20°; g = 50°
