Question

Please give the right answer and show work if possible

Answer 1

Answer:

B

Step-by-step explanation:

Sin 64=23/a. Let use trig identities to find other points

First, since sin and cos like are complementary angles we can use this formula

$\sin(x) = \cos(y) \: \: \: x + y = 90$

sin 64=23/a

$64 + x = 90$

$x = 26$

So cos 26=sin 64 so B is a answer
