Answer:
Midsegment of a Triangle Theorem
Step-by-step explanation:
Midsegment of a Triangle Theorem can be used to fill in the missing reason.
Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
Answer:
240 because first u have to figure out 40%of 50% and than 1200
Step-by-step explanation:
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

Now in Δ PQT and Δ QRS we have

Which are corresponding sides of a similar triangle in proportion.
∴ Δ PQT ~ Δ QRS .....{S-S-S test for similarity}...Proved
