I need help with this question please

9514 1404 393

  77

Step-by-step explanation:

The sum of the measures of the two given arcs is 180°, the measure of semicircle ADC. Using this fact, we can find x and the measure of DC.

  AD +DC = 180

  (19x -49) +(5x +37) = 180

  24x = 192 . . . . . . . . . . . add 12, simplify

  x = 8 . . . . . . . . . . divide by 24

Then the measure of DC is ...

  DC = 5x +37 = 5(8) +37 = 40 +37

  DC = 77

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7

hope it : ( : )

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
