Question

What is the value of x in the isosceles trapezoid below

Answer 1

Opposite angles of an isosceles trapezoid add up to 180.
(That graphic is very blurry.  I hope I can read it correctly.)
14x + 3x + 10 = 180
17x = 170
x = 10

Answer 2

Answer:

X=10

Step-by-step explanation:

In order to solve this problem you just have to remember that in rectangles and trapezoids opposite angles are suplemmentary, in this case you can equal those to 180º, your equation would be:

$14x+3x+10=180\\17x+10=180\\17x=180-10$

$17x=170$

$x=\frac{170}{17}$

$x=10$

So the answer is X equals to 10.
