Answer:
132+54+90=276
360-276= 84
Step-by-step explanation:
a circle has 360° so subtract all the given angles to find the missing one. yu can subtract each one by one or add all the given angles and subtract which I did
x = 84
a full circle is 360 and that small square means a right angle and right angles are always 90 degrees so 360-90-132-54=84
