How do you solve this? right triangle trigonometric sin(22°) = hypotenuse = 25 opposite = 18 adjacent = x this how i put it but idk what to do from there sin(22°) = 18/25

x = 23.2

Is you are just finding sin(22°) = 0.374

= 0.4

Step-by-step explanation:

since you are finding x (adjacent), then you have to use cos.

cos 22° = x/25

(multiply both sides by 25 to make x stand alone).

25(cos 22°) = x

x= 23.179

x= 23.2

2x^2+5x+17

your welcome. : )

b, i believe, but not sure.
