If the highest number is 8 then the answer I think would be 1/8.
A F is 309. 16 + 5 + 30 = 51. 360 - 51 = 309
Hope this helped :D
Base on the diagram you give and the choices where there is two triangle that both have vertexes, lines and segment. By calculating and analyzing the diagram , I conclude that the answer would be D. BD is congruent to RT. I hope i answered your question
