Measure the size of the angle between the 9cm and 6cm triangular sides to the nearest degree

This is a protractor question if you dont have one then try these on a calculator.

when angle is between two lines we need see where the hypotenuse is in the diagram and where is the adjacent.

And whether the triangle is right angle or not.

Try these

shift sin -1  x sin 9/6 (for opp/hyp)

shift sin -1  (9/6)   (for opp/hyp)

shift sin -1 x sin 6/9 (for opp/hyp)

shift sin -1 (6/9) (for opp/hyp)

shift cos -1 x cos 9/6 (for adj/hyp)

shift cos -1 (9/6) (for adj/hyp)

shift cos -1 x cos (6/9) (for adj/hyp)

shift cos -1 (6/9) (for adj/hyp)

shift tan -1 x tan (9/6) ( for opp/adj)

and so on
