Answer:
x=83
Step-by-step explanation:
The interior angle sums of a triangle always equal 180 degrees this is because it comes from the formula; (n-2)180 n is the number of sides so you have (3 -2) 180 = (1)180 = 180 now if we add all the angles together with it set to equal 180 we will have our equation
44+53+x=180 just simplify the 44 and 53
97+x= 180 Now subtract the 97 from both sides so the x is alone and equal to a value
x=83
