Question

Find the value of x if x, (2x+13),(3x+10) and (x-6)are all the angle of a quadrilateral.

Answer 1

Answer:

Step-by-step explanation:

All angles of a quadrilateral are equal to 360°

So,

x+(2x+13)+(3x+10)+(x-6)=360°

Adding the above,we get

7x+17=360°

7x=360°-17°

7x=343

x=343/7

x=49
