Question

2. The measure of two adjacent angles of a parallelogram are (3x - 4) and (3x + 4) find the measure of each angles of a parallelogram.​

Answer 1

To find :

angle measure of each angle of the parallelogram

Given :

the adjacent angles of the parallelogram are 3x-4 and 3x+ 4.

Always remember :

• opposite angles of a parallelogram are equal
• the sum of adjacent angle is 180°

Solution :

3x-4 and 3x+4 are adjacent angles , hence

the 3x+4+3x-4 = 180°

or, 6x = 180°

or, x = 30°

so, the angles are :

• 86°
• 94°
• 86
• 94°
