Answer :

**Formula Used/Theory:-**

Angle sum property

Sum of all angles of triangle is 180°

In the right angled triangle where x lies

One angle is 55°

Other angle is x

And central angle is 90°

Then by angle sum property

55° + x + 90° = 180°

x + 145° = 180°

x = 180° - 145° = 35°

**Result:-** the value of x comes out to be 35°
