Answer:
should be 80, angle 50 is congruent on both sides to 50+50 equals 100. The triangle sum theorem says a triangle adds up to 180 degrees so we are left with 80, X=80 degrees

Answer:
A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones
Step-by-step explanation:
B. table : (8,8)(12,12)(14,16)(16,16)
                look at ur points...when x = 8, y = 8...so the table, when x = 8 has a 
                value of 8
relation : f(x) = 8x - 5....when x = 8
              f(8) = 8(8) - 5
              f(8) = 64 - 5
              f(8) = 59....and the relation has a value of 59
Therefore, the relation has a greater value when x = 8 <==
C. f(x) = 8x - 5...when f(x) = 19
     19 = 8x - 5
      19 + 5 = 8x
     24 = 8x
     24/8 = x
     3 = x <==
