Question

Solve this parallelogram angle

Answer 1

103°

Explanation:

Hint :

• sum of angles of quadrilateral = 180°

Simplify:

77° + x° = 180°

x° = 180° - 77°

x° = 103

Answer 2

103

Explanation:

angles formed on the same line of a parallelogram are supplementary angles

( the angle with the measure of 77 degrees and the angle labeled "x" are formed on the same line which means they are supplementary )

supplementary angles add up to equal 180

hence, 77 + x = 180

180 - 77 = 103

Hence, x = 103
