Question

WXYZ is an isosceles trapezoid. WY=8x-3 and ZX=19. Find the value of x.

Answer 1

Given:

WXYZ is an isosceles trapezoid. WY=8x-3 and ZX=19.

To find:

The value of x.

Solution:

We know that the diagonals of an isosceles trapezoid are equal. So,

`WY=ZX`

`8x-3=19`

Add 3 on both sides.

`8x-3+3=19+3`

`8x=22`

Divide both sides by 8.

`x=(22)/(8)`

`x=2.75`

Therefore, the correct option is B.
