Question

find the value of x if x,(2x +13),(3x+10°) and (x-6) are all the angles of a quadrilateral.​

Answer 1

Answer:

x=49

Step-by-step explanation:

sum of angles of a quafrilateral =360

x+(2x+13)+(3x+10)+(x-6)=360

7x+13+10-6=360

7x+17=360

7x=360-17

7x=343

x=343/7

x=49

Answer 2

Answer:

Step-by-step explanation:

We know that sum of all angles of a quadrilateral is 360°

x+(2x+13) +(3x+10) +(x-6) =360°

7x+17=360°

7x=360-17

7x=343

x=343÷7

x=49
