Question

2. Two adjacent angles of a parallelogram are (3x - 4)º and (3x + 16)°. Find
the value of x and hence find the measure of all the angles of the
parallelogram​

Answer 1

Answer:

80°, 80°, 100° and 100°

Step-by-step explanation:

The adjacent angles of a parallelogram are supplementary.

=> 3x-4+3x+16 = 180°

=> 6x+12 = 180°

=> 6x = 180-12

=> 6x = 168

=> x = 168/6

=> x = 28

Hence, the angles are 80°, 80°, 100° and 100°.
