The angles of a qaudileteral are x,2x,100 and 110 degress find the value of 2x

Step-by-step explanation:

Hey there

We generally sum up all the angles to get 360° as per given in our question.

Here, in your question, we have values as,

x, 2x, 100°, 110°.

(We have 360° as the sum quadrilateral).

So, x° + 2x° + 100°+110° = 360°

3x°+210°= 360°

3x° = 360° - 210°

or, 3x° = 150°

Therefore the measure of 2x is (2×50)°=100°.

Hopeit helps...

X=50; 2x=2×50=100

Step-by-step explanation:

sum of angles in a quadrilateral is 360°

Therefore; x+2x+100+110=360;

3x+210=360;

3x=360-210;

3x=150;

divide both sides by the co-efficient of x;

3x/3=150/3;

x=50;

therefore 2x=2×50;

2x=100.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
