In a classroom of 28 students: 19 of the students have brown eyes 13 of the students wear glasses 7 of the students do not have brown eyes or glasses how many brown-eyed students wear glasses? answer

Total students = 28

Students with brown eyes = 19

students wear glasses = 13

Not brown eyes or no glasses = 7

Not brown eyes = 28 - 19 = 9

Not wearing glasses = 28 - 13 = 15

Not brown eyes and wearing glasses = 15 - 9 = 6

Brown eyes and wearing glasses = 13 - 6 = 7 < answer

7 is the answer

Step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
