Answer:


x = 50

Explanation:

Sum of the interior angles in a quadrilateral

= 360°

Let's solve now


x + 10 + 3x + x + 2x = 360 \\ 7x + 10 = 360 \\ 7x = 360 - 10 \\ 7x = 350 \\ (7x)/(7) = (350)/(7) \\ x = 50

hope this helps you.

Answer:

x = 50

Explanation:

Since this is a quadrilateral, the sum is 360 degrees

2x+x+10 + 3x+x = 360

Combine like terms

7x+10 =360

Subtract 10 from each side

7x+10-10 = 360-10

7x = 350

Divide by 7

7x/7 = 350/7

x = 50
