ΔABC and ΔXYZ are similar triangles. If BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4, find the value of x.
Nat2105 [25]

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

\frac{x+9}{x+5}= \frac{x+7}{x+4}\\
\\
(x+9)(x+4)=(x+7)(x+5)\\
\\
x^2+13x+36=x^2+12x+35\\
\\
13x-12x=35-36\\
\\
x=-1\\
\\

Hence then value of x=-1.

eduard

Answer: the first answer

Step-by-step explanation: sorry i know it would’ve been better if i typed it but i’m running out of charge so it would be you first answer. this is because domain shows the minimum and maximum values x can be and range is the same but for y. the second and third functions aren’t in any format that i’ve learned before and it’s closest to interval notation which can be written as [min,max] with parentheses if it doesn’t touch those values. but yeah i hope this helped and i’m sorry if it is incorrect. good luck!
