Answer:
18 students.
Step-by-step explanation:
Total amount is 100
Take 68 and add to 60 to get 128.
Subtract from both numbers until you get to 50.
68 needs 18 subtracted to get to 50.
60 needs 10 to get to 50.
18 plus 10 is 28, which is the excess.
Here, 18 people like only football.
i think 40
if 68 =likes foot ball
&60=likes volley ball
here there are available the students that likes both because 68+60=128 but the students are 100 so the students that likes both are 128-100=28
threfore the students that like only football are 40
cause the 68 likes football & the28 likes only football
so to know how many students likek foot ball evaluate like this (68-28=40)
i hope helps you
tanA = sinA / cosA = 3/5 / 4/5 = 3/4.
