Answer:
-9
Step-by-step explanation:
2x + 7 = -11
2x = -11 - 7
2x = -18
x = -9
Answer:
Δ PQT ~ Δ QRS .....{S-S-S test for similarity}...Proof is below.
Step-by-step explanation:
Given:
In Δ PQT
PQ = 30 ft
QT = 28 ft
TP = 20 ft
In Δ QRS
QR = 15 ft
RS = 14 ft
SQ = 10 ft
To Prove:
Δ PQT ~ Δ QRS
Proof:
First we consider the ratio of the sides
..............( 1 )
..............( 2 )
..............( 3 )
So By equation ( 1 ), ( 2 ) and ( 3 ) we get
![\frac{PQ}{QR}=\frac{QT}{RS} = \frac{TP}{SQ}](https://tex.z-dn.net/?f=%5Cfrac%7BPQ%7D%7BQR%7D%3D%5Cfrac%7BQT%7D%7BRS%7D%20%3D%20%5Cfrac%7BTP%7D%7BSQ%7D)
Now in Δ PQT and Δ QRS we have
![\frac{PQ}{QR}=\frac{QT}{RS} = \frac{TP}{SQ}](https://tex.z-dn.net/?f=%5Cfrac%7BPQ%7D%7BQR%7D%3D%5Cfrac%7BQT%7D%7BRS%7D%20%3D%20%5Cfrac%7BTP%7D%7BSQ%7D)
Which are corresponding sides of a similar triangle in proportion.
∴ Δ PQT ~ Δ QRS .....{S-S-S test for similarity}...Proved
