Given:

In the given figure,
\angle W\cong \angle T, WS = 5, WR = 4x+3, RT=7x+3 and VT=8.

To find:

The measure of WR and RT.

Solution:

In triangles WRS and TRV,


\angle W\cong \angle T (Given)


\angle WRS\cong \angle TRV (Vertically opposite angles)


\triangle WRS\sim \triangle TRV (AA property of similarity)

We know that the corresponding sides of similar triangles are proportional. So,


(WR)/(WS)=(RT)/(VT)


(4x+3)/(5)=(7x+3)/(8)


8(4x+3)=5(7x+3)


32x+24=35x+15

Isolate the variable x.


24-15=35x-32x


9=3x

Divide both sides by 3.


(9)/(3)=x


3=x

Now,


WR=4x+3


WR=4(3)+3


WR=12+3


WR=15

And,


RT=7x+3


RT=7(3)+3


RT=21+3


RT=24

Therefore, the measure of WR is 15 units and the measure of RT is 24 units.
