mrs_skeptik [129]

Answer:

370

Step-by-step explanation:

The venn diagram corresponds to students who were sick in January at a Chicago high school.

Students who had only fever= n(A) = 80

Students who had only headache= n(B) = 90

Students who had only cough  = n(C) =60

Students who had both cough and fever = n(AC) = 10

n(AB) = 40:n(BC) = 30  n(ABC) = 20

Hence total students = 800

no of students who were absent due to other reasons = 100

REmaining students = 700

Students who were sick = sum of all =330

So no of students who were at school = 700-330 = 370

\\ \sf\Rrightarrow \dfrac{15}{20}=\dfrac{21}{28}

\\ \sf\Rrightarrow \dfrac{1}{4}=\dfrac{1}{4}

Hence they are similar

  • <A=<H
  • And ratio of sides are same

Hence both triangles are similar by SAS property

#3

\\ \sf\Rrightarrow ∆KDH\sim ∆ABD
