Answer:
x=50.7°
Step-by-step explanation:
Use the given angle of x° to find which trigonometry ratio to use. We are given the side adjacent to the angle and the hypotenuse. Therefore, we use the cosine ratio:
[tex]cosineX=\frac{adjacent}{hypotenuse}[/tex]
Insert the given values:
[tex]cos.x=\frac{19}{30}[/tex]
In order to fin the angle, use the inverse:
[tex]x=cos^{-1}(\frac{19}{30} )[/tex]
Insert the equation into a calculator:
[tex]x=50.70351976[/tex]
Round to the nearest tenth:
[tex]x=50.7[/tex]
:Done
