Question

if tan A =3/4 ,find the value of 1/sinA+1/cos A...answer please​.. please​

Answer 1

Answer:

tana=3/4

sec²A=1+tan²A

=1+(3/4) ²

=1+9/16

sec²A=25/16

secA=5/4

cosA=4/5

sin²A+cos²A=1

sin²A=1-cos²A

=1-(4/5) ²

=1-16/25

sin²A=9/25

sinA=3/5

1/sinA+1/cosA

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

5/3+5/4

35/12
