Question

in a right angle triangle tan a=1,
find sin a and cos a

Answer 1

Answer:

tan a = 1

but tan 45 = 1

So by comparison of angles we get

a = 45

So,

sin 45 = 1/root 2

and

cos 45 = 1/root 2

Answer 2

Step-by-step explanation:

tana = 1

tana = tan45

=> a = 45

sina = sin45

= root3/2

cosa = cos45

= root 3/2
