Given:
In the given figure,
, 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,
(Given)
(Vertically opposite angles)
(AA property of similarity)
We know that the corresponding sides of similar triangles are proportional. So,
![(WR)/(WS)=(RT)/(VT)](https://img.qammunity.org/2022/formulas/mathematics/college/xt8sp4d60gk2au4p3dxvizcjpd705ve648.png)
![(4x+3)/(5)=(7x+3)/(8)](https://img.qammunity.org/2022/formulas/mathematics/college/kyng4cvqohm3o71ue94p8qpmdoctr7hbmj.png)
![8(4x+3)=5(7x+3)](https://img.qammunity.org/2022/formulas/mathematics/college/wsnjrrmz7za7jdj6u5xbpuzf3j5v04syus.png)
![32x+24=35x+15](https://img.qammunity.org/2022/formulas/mathematics/college/8485f4kvegg8f524oheqftobqnck898ygi.png)
Isolate the variable x.
![24-15=35x-32x](https://img.qammunity.org/2022/formulas/mathematics/college/q5adfgflboq5kc3mql06msqqiyovfrgldn.png)
![9=3x](https://img.qammunity.org/2022/formulas/mathematics/college/pdivtvlbxovk8g3gbsh181cjrvhjqf9aap.png)
Divide both sides by 3.
![(9)/(3)=x](https://img.qammunity.org/2022/formulas/mathematics/college/uzrfux5u54ks38lb60bvwtigcq3qkxd0jt.png)
![3=x](https://img.qammunity.org/2022/formulas/mathematics/high-school/m7iw8xgyl1pxt09wm45n2c8c8sf0m8u6kn.png)
Now,
![WR=4x+3](https://img.qammunity.org/2022/formulas/mathematics/college/mg3ojuaovk7wd033tz5q0ae4dxn00pzusx.png)
![WR=4(3)+3](https://img.qammunity.org/2022/formulas/mathematics/college/jhefm58lys25kr43b00qjptwnls6u7v9rj.png)
![WR=12+3](https://img.qammunity.org/2022/formulas/mathematics/college/4dqutibx7jksmaj7km78bveayeh3ynwgx4.png)
![WR=15](https://img.qammunity.org/2022/formulas/mathematics/college/x99vdeogsmpqmwwzktqmz890d1uwnre5qf.png)
And,
![RT=7x+3](https://img.qammunity.org/2022/formulas/mathematics/college/8ryrcygco252m3yf5q6djx4apgqwr8mgch.png)
![RT=7(3)+3](https://img.qammunity.org/2022/formulas/mathematics/college/71el8m41ggugx6spavxfhzaibgxirtn1b5.png)
![RT=21+3](https://img.qammunity.org/2022/formulas/mathematics/college/wbak9pfxqyr625mmkoopzkxxzi3w012lrl.png)
![RT=24](https://img.qammunity.org/2022/formulas/mathematics/college/8pzft9w0hid8u9l43en84zip7vhumhq0tv.png)
Therefore, the measure of WR is 15 units and the measure of RT is 24 units.
