Question

The adjacent of the parallelogram PQRS are (2x - 13)and x +4.Find the measure of all the angles of parallelogram

Answer 1

Answer:

In a parallelogram, the sum of adjacent angles is 180degrees

Step-by-step explanation:

therefore, 2x-13+x+4=180

3x-9=180

3x=180+9

3x=189

x=189/3

x=63

2x-13=2(63)-13=126-13=113

x+4=63+4=67

In a parallelogram opposite angles are equal

theregore the angles of the parallelogram are113,67,113,67degrees
