22 Find The Measure Of Angle B class=

Sagot :

Answer: Approximately 51.06 degrees

Work Shown:

[tex]\sin(\text{angle}) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin(\text{B}) = \frac{\text{AC}}{\text{AB}}\\\\\sin(\text{B}) = \frac{7}{9}\\\\B = \sin^{-1}\left(\frac{7}{9}\right)\\\\B \approx 51.0575587^{\circ}\\\\B \approx 51.06^{\circ}[/tex]
