Given that BC = 10


\propto\text{ = 25}

AC is the hypotenuse

BC is the opposite angle of alpha

AB is the adjacent

To get Beta


\begin{gathered} \beta\text{ = 180 - }\alpha\text{ - 90} \\ \beta\text{ = 180 - 25 - 90} \\ \beta\text{ = 65} \end{gathered}

To get AC, we can use the trigonometric function


\sin \text{ 25=}(10)/(AC)

AC = 10/ sin 25

AC = 10/ 0.423

AC = 23.662

To get AB


\tan \text{ 25 = }(10)/(AB)

AB = 10 / tan 25

AB = 10 / 0.466

AB = 21. 445

If, BC = 10 and the angle a = 25 degrees, find any missing angles or sides. Give your-example-1
