Solution:
we are given that ΔABC and ΔXYZ are similar triangles.
As we know , when two triangles are similar then the ratios of their corrsponding sides are equal.
Here we have
BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4
So we can write
Hence then value of x=-1.
Answer:
Find out the what is the price of oranges this week .
To prove
As given
last week the price of oranges at the farmers market was $1.75 per pound.
This week a price has decreased by 20% .
20% is written in the decimal form
= 0.20
Decreased in the price = 0.20 × 1.75
= $0.35
The price of oranges this week = Price of orange at last week - Decreased in the price
= $1.75 - $0.35
= $ 1.4
Therefore the price of oranges this week is $1.4 .
