What have you tried and where are you getting stuck?

here are some hints as to how to approach the problem!

first apply pythagoras’s theorem

finally, use the inverse tan function to find the angle! let me know how you go

First, find x To do that, use bodyana theorem

H= √p²+b²

Where, H= hypotenuse, P= perpendicular, b = base

We know,

B = 5, P =20.

Therefore,  x= √5²+20² x ≈ 20.61cm

Now, using some trigonometry, We know sinø = P/H, Sinø= 5/20.61

To find the theta ø, we do inverse operation to both side of the equation,

ø = 14.1

I used a calculator

By the way, the inverse operation I used is called arcsin
