Find the length using Trigonometry and Pythagoras when applicable.

The length of x = 22.69 cm
We can solve this triangle by taking Sin theta because we know that
Sin = Perpendicular / Hypotenuse
We are given with 52 degree and hypotenuse is 23 cm so
Sin 52 = Perpendicular / 23
0.9866 = Perpendicular / 23
0.9866 x 23 = Perpendicular
22. 69 cm
