Question

In an isosceles trapezoid, two angles are labeled as shown. What is the value of x?

Answer 1

153+3x+15=180

Answer 2

Answer choices:

3

4

23

46

Answer 3

Well something is wrong then because opposite angles of an isosceles trapezoid are supplementary. So x = 2/3 and 3x+15= 17 so you have posted something incorrectly.

Answer 4

Idk, I copy and pasted?! Lol

Answer 5

You copied and pasted the picture but not the answers or the question. Maybe you got the wrong list of answers or the wrong question for that picture.

Answer 6

No, I just double checked.. :\

Answer 7

Well then, you look it up. Aren't the opposite angles of an isosceles trapezoid supplementary?

Answer 8

Did you look it up?

Answer 9

I looked and it just confused me, a lot.
None of the sites I just looked on are consistent with an answer.

Answer 10

Nope, you're right. Indeed, supplementary.

Answer 11

the opposite angles of an isosceles trapezoid are always supplementary, i.e.they sum to 180 degrees.

Answer 12

Hm..

Answer 13

So now we know that the equation is true: 153 + 3x+15 = 180
3x+168=180
3x=12
x=4

Answer 14

I must have made a mistake when i solved it before. Sorry

Answer 15

Aha thank you so much!
