Question

if tan A=¾ find the value of 1/sinA+1/cosA​

Answer 1

Answer:

tan a =  3/4

formula = tan a = p/b

      p = 3 , b= 4 , h = ?

(p)^2 + (b)^2 = (h)^2

(3)^2 +(4)^2 = (h)^2

9 + 16 = (h)^2  

25 = (h)^2

h = 5

sin a = p/h

     = 3/5

cos a = b/h

      = 4/5

1/sina +1/cosa =

1/(3/5)+ 1/(4/5)= 5/3+5/4

20+15/12= 35/12

so 35/12 is the required answer

hope you understand . and ask me if not understand !!
