Question

Please give the right answer and show work if possible

Answer 1

B

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
