Question

Tell whether the angles are complementary or supplementary. Then find the value of x.

Answer 1

Supplementary angles,

x = 50

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
