Let's use Trigonometric relations to find the value of hypotenuse (x), in the given right angled Triangle.

$\qquad \sf \dashrightarrow \: \cos(45) = \dfrac{11}{{x}^{} }$

$\qquad \sf \dashrightarrow \: \dfrac{1}{ \sqrt{2} } = \dfrac{11}{x}$

$\qquad \sf \dashrightarrow \: x = 11 \times \sqrt{2}$

$\qquad \sf \dashrightarrow \:x = 11 \sqrt{2 \:} \: units$

ankoles [38]

Answer:

4 students

Step-by-step explanation:

The total number of students is given by:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N$

Where N is the total number of students, A is the number of students that have taken Math 2A, B is the number of students that have taken Math 2B, and C is the number of students that have taken Math 2C:

$|A|+|B|+|C|-|A\cap B|-|A\cap C|-|B\cap C| + |A\cap B \cap C| = N\\51+80+70-15-20-13 + |A\cap B \cap C| = 157\\ |A\cap B \cap C| =4$

4 students in Group A have taken all three classes.

*The number of students that have taken two classes has be subtracted so those students do not get counted twice
