If the cos 23° = two thirds, then the sin 67° =

Step-by-step explanation:

Note the cofunction identity

cos x° = sin(90 - x)°, hence

cos23° = sin(90 - 23)° = sin67°, thus

cos23° = sin67° =

sin 67° =  

Step-by-step explanation:

If cos 23° =

Then we have to find the value of sin 67°

Since we know

cosx = sin (90-x)

so cos 23 = sin ( 90 - 23 )

                = sin ( 67)

= sin 67°

Therefore, sin 67° =   will be the answer.

the answer is c 150
