Question

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

Answer 1

I got 28 but idk if thats right

Answer 2

well, these are vertically opposite angles, and in an isosceles trapezium they are supplementary, that is they add upto 180 degrees.

Answer 3

Opposite angles of an isosceles trapezoid are always supplementary. Does that help?

Answer 4

first set an equation like this:

\( \color{Black}{\Rightarrow 124 + (4x + 12) = 180 }\)

this is the supplementary angle theorem.

Answer 5

so,

(4x+12)+124=180

solve and find 'x'!

Answer 6

so is it x = 11

Answer 7

am sorry, but 28 isn't correct.


yes x=11 is CORRECT-O!!
