Answer:

39°

Step-by-step explanation:

If it gives you 2 angles and asks for x, you know it has 3 angles. So the shape is a triangle. All 3 angles in a triangle add up to 180°.

So add 78 and 63 which equals 141

[tex]78+63=141[/tex]

And to find x, subtract 141 from 180 because 180 is the total.

[tex]180-141=39[/tex]

So the answer is 39
