Question

please help me find the diagonal.

Answer 1

The diagonals of an isosceles trapezoid are congruent.
So, AC = BD which gives x + 1 = 2x-3.
Solve for x and back-substitute into x or 2x - 3 to get the diagonal length.

Would you solve this for x?
Someone will check your answer if you like. @Foreverisabell
x + 1 = 2x-3

Answer 2

@Directrix wait so the equation is x + 1 = 2x -3

Answer 3

I don't know what to do from the point 3x = -2?

Answer 4

> wait so the equation is x + 1 = 2x -3

Yes, it is.
I think you made a mistake in your solution.

x + 1 = 2x -3
Subtract x from both sides:

That gives 1 = x - 3
Then, add 3 to both sides to get x.
So, x = ?

@Foreverisabell

Answer 5

-2 = x

Answer 6

@Directrix

Answer 7

@Foreverisabell

That gives 1 = x - 3
Then, add 3 to both sides to get:

4 = x.

After that, substitute x = 4 into x + 1 to get the diagonal length.

4 + 1 = ? for the diagonal
