For this case, we must indicate how many students there are in the class knowing that it includes 14 "lefties". For this, we make a rule of three:

20 -------------> 4

x ---------------> 14

Where the variable "x" the number of students in the class.

x = \frac {14 * 20} {4}\\x = \frac {280} {4}\\x = 70

Thus, if the class includes 14 left-handers, then according to the base average, the class will have a total of 70 students.

Answer:

70 students

The number in the class is 20/4 = 5 times the number of "lefties."

  5 · 14 = 70

The class is estimated to have 70 students.

The bigger triangle has a 90 degree corner add that to 64 and you will get 164 (all of the triangles angles have to add to 180) from 180 subtract 164 and you get 26 which is C's answer

For D just divide 90 by 2 (90/2)=45
