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.

$x=\dfrac{22}{8}$

$x=2.75$

Therefore, the correct option is B.
