X + y = 12
x - y = 4
(12 - 4) : 2 = 4
4 + 4 = 8
x = 8
y = 4
-----------------------
8 + 4 = 12
8 - 4 = 4
Step-by-step explanation:
Hey there!
From the given figure;
An exterior angle is 127°.
To find: value of"X"
Now;
x+127° = 180°. [Being linear pair]
or, X = 180° - 127°
or, X = 53°
Therefore, the value of "X" is 53°.
