Question

if sin teta =3/4 then the value of cos teta anda tan tetaif sin theta equal to 3 by 4 then the value of the cos theta and tan theta ​

Answer 1

Step-by-step explanation:

let theta = A ( easier to type)

here ,

sin A =3/4 = perpendicular/ hypotenenous =p/h

therefore

p=3

h=4

we know that

b= (h²-p²)^(1/2)

b=( 4²- 3²) ^(1/2)

b=7 ^ (1/2)

b=under root 7

hence ,

cos A =b/h =( under root 7)/4

tan A =p/b =3/(under root 7)
