A triangle's angles (in all) = 180 degrees
78 + 27 + x = 180
simplify:
78 + 27 + x = 180
105 + x = 180
subtract 105 from both sides
x + 105 (-105) = 180 (-105)
x = 180 - 105
x = 75
°
is your answer
hope this helps

Hi there!
Since the sum of all angles in any triangle always equals 180°, we can just subtract to find x.
180 - 27 - 78
= 153 - 78
= 75
So, the value of x is 75°.
Hope this helps!
