Answer:
Supplementary angles,
x = 50
Step-by-step explanation:
These angles are supplementary, meaning that they add up to form a 180-degree angle or a straight line.
Knowing this, now form and solve the equation,
76 + 2x + 4 = 180
Combine like terms,
76 + 2x + 4 = 180
80 + 2x = 180
Inverse operations,
80 + 2x = 180
-80 -80
2x = 100
/2 /2
x = 50
