Question

2 adjacent angles of a parallelogram are (2x+30) °+(3x+30) °.Find the value of x​

Answer 1

We know that adjacent angles of a parallelogram are supplementary.

Then,a/q

(2x+30)+(3x+30)=180

5x+60=180

5x=180-60

5x=120

x=120/5

x=24

Answer 2

Answer

we know that

2 adjacent angles of a parallelogram are Suplimentary

=>(2x+30) +(3x+30) °=180°

=5x+60=180°

Step-by-step explanation:

(2x+30) +(3x+30) °=180°

2x+30 +3x+30 °=180°

=5x+60=180°

5x=180°-60°

5x=120°

x=120°÷5

x=24

therefore x=24
