In right abc, b is a right angle and sin c = x. cos a =

C. .

Step-by-step explanation:

We have been given that in right right ABC, B is a right angle and . We are asked to find .

We will use basic trigonometric identity to solve our given problem.

Since B is the right angle, so by angle sum property

Since , therefore, by identity ; .

Therefore, option C is the correct choice.

c is the answer

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
