Find the value of x. (1. Label the sides, 2. Figure out which function, 3. Set up, 4. Solve) THE FUNCTIONS ARE AT THE BOTTOM Will give brainliest for full answer

1) x = 19.6, cos, cos(40) = x/15

2) x = 9.6, tan, tan(21) = x/25

3) x = 9.2, sin, sin(16) = x/33.5

4) x = 29.8, sin, sin(50) = 22.8/x

5) x = 32.3, tan, tan(30) = x/56

Hopefully this helps :)

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

your answer is option c.
