Question

Please help me out!!!!!.........

Answer 1

x=50

Explanation:

The total number of angles in a quadrilateral is 360.

set the expressions you have as equal to 360

(x+10)+3x+2x+x = 360

collect the x terms together

7X + 10 = 360

subtract the 10 to get just "x"s on one side

7X = 350

divide by 7 to get X alone

x = 50

Answer 2

x = 50°

Explanation:

Angles in a quadrilateral sum to 360°

From the angles given, we can set up an equation

( x + 10 ) + ( 3x ) + ( 2x ) + ( x ) = 360

Now we solve it

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

(Add the like terms together)

7x + 10 = 360

( -10 from both sides)

7x = 350

( ÷ both sides by 7)

x = 50°
