1 answer:
Answer: D) 8 inches
====================================================
Work Shown:
Refer to the diagram below.
A = 50 degrees
B = unknown
C = 80 degrees
-----
For any triangle, the three angles always add to 180
A+B+C = 180
50+B+80 = 180
B+130 = 180
B = 180-130
B = 50 degrees
Since angles B and C are the same measure, their opposite sides are the same length. Triangle ABC is isosceles. Therefore, a = x = 8
