Answer:
X= 143°
Step-by-step explanation:
You could do it your way or as you can see, there's a right angle, which equals 90°, so you could either add 44+46+53 or 90+53. You get the same answer, which is 143°.
53°+44°+46°+x=360°(complete circle)
or,143°+x=360°
or,x=360°-143°
or,x=217°
hope this helps you.
