Question

if two adjacent angles of a parallelogram are 5 x minus 5 degree and 10 x minus 35 degree then the value of x is​

Answer 1

Answer:

14.6666

Step-by-step explanation:

The two adjacent angles of a parallelogram are equals to 180 degrees

Then (5x-5)+(10x-35)=180

5x-5+10x-35=180

5x+10x-5-35=180

15x-40=180

15x=180+40

Because -40 becomes +40 when it goes opposite side of equal

15x=220

x=220/15

x=14.666
