Answer:

40°

Explanation:

As we have,


\rm\hookrightarrowThe Sum of all sides of a triangle is 180°

Now,


\rm\hookrightarrow 79+x+52+x+73=180\\\\\rm\hookrightarrow x=180-79-52-73\\\\\rm\hookrightarrow x=-12

Again, finding the measure of ∡A by putting the value of x.


\rm\hookrightarrow x+52\\\\\rm\hookrightarrow -12+52\\\\\rm\hookrightarrow 40
