Work out size of angle x

angle x = 84°

Step-by-step explanation:

To find angle x, we have to know that the sum of angle in a circle  is 360°  and a right angle is 90°

Which implies, If we are to add the angles i  the figure above, it will give 360°

We will equate the sum of the angles to 360°. That is;

x + 90°+54°+ 132° = 360°

x + 276°  = 360°

Subtract both-side of the equation by 276°

x + 276°-  276°    = 360° -  276°  

x = 84°

Therefore angle x = 84°
