Question

What’s the answer help pls

Answer 1

7

Explanation:

Triangle Proportionality Theorem : If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

`(RP)/(PT)` =
`(SQ)/(QT)` Set up proportions

`(6)/(18)` =
`(x)/(21)` Cross multiply

18x = 126 Divide to isolate x

x = 7

Answer 2

Explanation:

rp= 6 cm and as u can tell the side where q,s lies is a little bit longer so itll be 1 cm longer the r,p!!
