Question

If TU=z+9 and VX=z–41, what is VX? Picture down below.

Answer 1

VX=50

Explanation:

VX=
`(1)/(2) *UT` (The straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.

`z-41=(1)/(2) *z+9`

`z-41=z+9/2`

do cross multiplication

2(z-41)=z+9

2z-82=z+9

2z-z=9+82

z=91

VX=z-41

=91-41

=50
