Question

if cos=60/61 then find value of sin, cosec & sec​

Answer 1

Step-by-step explanation:

cos =60/61 =B/H

By P.T

h²=p²+b²

61²=p²+60²

3721=p²+3600

p²=3721-3600

p²=121

p= √121

p= 11

from above p=11 b=60 and h=61

we know that sin=p/h cosec=h/b sec=h/p

therefore

sin=11/61

cosec=61/60

sec=61/11
