To find the value of the missing angle, use Pythagoras theorem

a² = b² + c²

Where a is the hypotenuse, b opposite side and c the adjacent side

So in this case we need to identify the sides

The opposite side is 9.9 and the adjacent side is 5

Then replace on the formula

a² = b² + c²

a² = (9.9)² + (5)²

a = /
