Question

Finding Sin and Cos

I attached a picture of the triangle needed to solve these problems:

1. Find sin A.
a) 4/3
b) 4/5
c) 3/5
d) 3/4

I got answer C. Is that right?

2. Find cos A.
a) 4/3
b) 4/5
c) 3/5
d) 3/4

I got answer B. Correct?

Thank you for helping :)

Answer 2

yes, you are correct.
