Question

IF sin o =3by4 calculate cos a =tan a and cot a

Answer 1

Answer:

sin a =3/4

cos a=tan a

sina / cos a= 3/4×cos a

tan a = 3/4 tan a. ( cos a= tan a)

tan ²a = 3/4

tan a = √3/2

Answer 2

Step-by-step explanation:

sin theta=3/4

sin ²theta + cos²theta =1

(3²/4²)-1=cos² theta

9/16-1=cos²theta

16+9/16= cos² theta

25/16 = cos² theta............(removing square)

5/4= cos theta

TO FIND TAN THETA

SIN THETA/COS THETA= TAN THETA

3/4/5/4= TAN THETA

3/5= TAN THETA
