We can calculate using cosinus method in triangle
c² = a² + b² - 2ab cos c
Plug in the number to the formula
c² = a² + b² - 2ab cos c
c² = 10² + 8² - 2(10)(8) cos 105°
c² = 100 + 64 - 160 cos 105°
c² = 164 - 160 (-0.26)
c² = 164 + 41.6
c² = 205.6
c = √205.6
c =14.34
C is 14.34 unit length

She missed 3 questions, 
11/100 equals x/26 
^set up this proportion 
you get 286 equals 100x
and x equals 2.86
round this to 3 questions
to check your work, do 23/26
